Use if_maddr_rlock()/if_maddr_runlock() rather than IF_ADDR_LOCK()/
IF_ADDR_UNLOCK() across network device drivers when accessing the
per-interface multicast address list, if_multiaddrs.  This will
allow us to change the locking strategy without affecting our driver
programming interface or binary interface.

For two wireless drivers, remove unnecessary locking, since they
don't actually access the multicast address list.

MFC r189714:
  bus_dma(9) conversion and make txp(4) work on all architectures.
  o Header file cleanup.
  o bus_dma(9) conversion.
    - Removed all consumers of vtophys(9) and converted to use
      bus_dma(9).
    - Typhoon2 functional specification says the controller supports
      64bit DMA addressing. However all Typhoon controllers are known
      to lack of DAC support so 64bit DMA support was disabled.
    - The hardware can't handle more 16 fragmented Tx DMA segments so
      teach txp(4) to collapse these segments to be less than 16.
    - Added Rx buffer alignment requirements(4 bytes alignment) and
      implemented fixup code to align receive frame. Previously
      txp(4) always copied Rx frame to align it on 2 byte boundary
      but its copy overhead is much higher than unaligned access on
      i386/amd64. Alignment fixup code is now applied only for
      strict-alignment architectures. With this change i386 and
      amd64 will get instant Rx performance boost. Typhoon2 datasheet
      mentions a command that pads arbitrary bytes in Rx buffer but
      that command does not work.
    - Nuked pointer trick in descriptor ring. This does not work on
      sparc64 and replaced it with bcopy. Alternatively txp(4) can
      embed a 32 bits index value into the descriptor and compute
      real buffer address but it may make code complicated.
    - Added endianness support code in various Tx/Rx/command/response
      descriptor access. With this change txp(4) should work on all
      architectures.
  o Added comments for known firmware bugs(Tx checksum offloading,
    TSO, VLAN stripping and Rx buffer padding control).
  o Prefer faster memory space register access to I/O space access.
    Added fall-back mechanism to use alternative I/O space access.
    The hardware supports both memory and I/O mapped access. Users
    can still force to use old I/O space access by setting
    hw.txp.prefer_iomap tunable to 1 in /boot/loader.conf.
  o Added experimental suspend/resume methods.
  o Nuke error prone Rx buffer handling code and implemented local
    buffer management with TAILQ. Be definition the controller can't
    pass the last received frame to host if no Rx free buffers are
    available to use as head and tail pointer of Rx descriptor ring
    can't have the same value. In that case the Rx buffer pointer in
    Rx buffer ring still holds a valid buffer and txp_rxbuf_reclaim()
    can't fill Rx buffers as the first buffer is still valid. Instead
    of relying on the value of Rx buffer ring, introduce local buffer
    management code to handle empty buffer situation. This should fix
    a long standing bug which completely hangs the controller under
    high network load. I could easily trigger the issue by sending 64
    bytes UDP frames with netperf. I have no idea how this bugs was
    not fixed for a long time.
  o Converted ithread interrupt handler to filter based one.
  o Rearranged txp_detach routine such that it's now used for general
    clean-up routine.
  o Show sleep image version on device attach time. This will help
    to know what action should be taken depending on sleep image
    version. The version information in datasheet was wrong for newer
    NV images so I followed Linux which seems to correctly extract
    version numbers from response descriptors.
  o Firmware image is no longer downloaded in device attach time. Now
    it is reloaded whenever if_init is invoked. This is to ensure
    correct operation of hardware when something goes wrong.
    Previously the controller always run without regard to running
    state of firmware. This change will add additional controller
    initialization time but it give more robust operation as txp(4)
    always start off from a known state. The controller is put into
    sleep state until administrator explicitly up the interface.
  o As firmware is loaded in if_init handler, it's now possible to
    implement real watchdog timeout handler. When watchdog timer is
    expired, full-reset the controller and initialize the hardware
    again as most other drivers do. While I'm here use our own timer
    for watchdog instead of using if_watchdog/if_timer interface.
  o Instead of masking specific interrupts with TXP_IMR register,
    program TXP_IER register with the interrupts to be raised and
    use TXP_IMR to toggle interrupt generation.
  o Implemented txp_wait() to wait a specific state of a controller.
  o Separate boot related code from txp_download_fw() and name it
    txp_boot() to handle boot process.
  o Added bus_barrier(9) to host to ARM communication.
  o Added endianness to all typhoon command processing. The ARM93C
    always expects little-endian format of command/data.
  o Removed __STRICT_ALIGNMENT which is not valid on FreeBSD.
    __NO_STRICT_ALIGNMENT is provided for that purpose on FreeBSD.
    Previously __STRICT_ALIGNMENT was unconditionally defined for
    all architectures.
  o Rewrote SIOCSIFCAP ioctl handler such that each capability can be
    controlled by ifconfig(8). Note, disabling VLAN hardware tagging
    has no effect due to the bug of firmware.
  o Don't send TXP_CMD_CLEAR_STATISTICS to clear MAC statistics in
    txp_tick(). The command is not atomic. Instead, just read the
    statistics and reflect saved statistics to the statistics.
    dev.txp.%d.stats sysctl node provides detailed MAC statistics.
    This also reduces a lot of waste of CPU cycles as processing a
    command ring takes a very long time on ARM93C. Note, Rx
    multicast and broadcast statistics does not seem to right. It
    might be another bug of firmware.
  o Implemented link state change handling in txp_tick(). Now sending
    packets is allowed only after establishing a valid link. Also
    invoke link state change notification whenever its state is
    changed so pseudo drivers like lagg(4) that relies on link state
    can work with failover or link aggregation without hacks.
    if_baudrate is updated to resolved speed so SNMP agents can get
    correct bandwidth parameters.
  o Overhauled Tx routine such that it now honors number of allowable
    DMA segments and checks for 4 free descriptors before trying to
    send a frame. A frame may require  4 descriptors(1 frame
    descriptor, 1 or more frame descriptors, 1 TSO option descriptor,
    one free descriptor to prevent descriptor wrap-around) at least
    so it's necessary to check available free descriptors prior to
    setting up DMA operation.
  o Added a sysctl variable dev.txp.%d.process_limit to control
    how many received frames should be served in Rx handler. Valid
    ranges are 16 to 128(default 64) in unit of frames.
  o Added ALTQ(4) support.
  o Added missing IFCAP_VLAN_HWCSUM as txp(4) can offload checksum
    calculation as well as VLAN tag insertion/stripping.
  o Fixed media header length for VLAN.
  o Don't set if_mtu in device attach, it's already set in
    ether_ifattach().
  o Enabled MWI.
  o Fixed module unload panic when bpf listeners are active.
  o Rearranged ethernet address programming logic such that it works
     on strict-alignment architectures.
  o Removed unused member variables in softc.
  o Added support for WOL.
  o Removed now unused TXP_PCI_LOMEM/TXP_PCI_LOIO.
  o Added wakeup command TXP_BOOTCMD_WAKEUP definition.
  o Added a new firmware version query command, TXP_CMD_READ_VERSION.
  o Removed volatile keyword in softc as bus_dmamap_sync(9) should
    take care of this.
  o Removed embedded union trick of a structure used to to access
    a pointer on LP64 systems.
  o Added a few TSO related definitions for struct txp_tcpseg_desc.
    However TSO is not used at all due to the limitation of hardware.
  o Redefined PKT_MAX_PKTLEN to theoretical maximum size of a frame.
  o Switched from bus_space_{read|write}_4 to bus_{read|write}_4.
  o Added a new macro TXP_DESC_INC to compute next descriptor index.

    descriptor access. With this change txp(4) should work on all
    architectures.
o Added comments for known firmware bugs(Tx checksum offloading,
  TSO, VLAN stripping and Rx buffer padding control).
o Prefer faster memory space register access to I/O space access.
  Added fall-back mechanism to use alternative I/O space access.
  The hardware supports both memory and I/O mapped access. Users
  can still force to use old I/O space access by setting
  hw.txp.prefer_iomap tunable to 1 in /boot/loader.conf.
o Added experimental suspend/resume methods.
o Nuke error prone Rx buffer handling code and implemented local
  buffer management with TAILQ. Be definition the controller can't
  pass the last received frame to host if no Rx free buffers are
  available to use as head and tail pointer of Rx descriptor ring
  can't have the same value. In that case the Rx buffer pointer in
  Rx buffer ring still holds a valid buffer and txp_rxbuf_reclaim()
  can't fill Rx buffers as the first buffer is still valid. Instead
  of relying on the value of Rx buffer ring, introduce local buffer
  management code to handle empty buffer situation. This should fix
  a long standing bug which completely hangs the controller under
  high network load. I could easily trigger the issue by sending 64
  bytes UDP frames with netperf. I have no idea how this bugs was
  not fixed for a long time.
o Converted ithread interrupt handler to filter based one.
o Rearranged txp_detach routine such that it's now used for general
  clean-up routine.
o Show sleep image version on device attach time. This will help
  to know what action should be taken depending on sleep image
  version. The version information in datasheet was wrong for newer
  NV images so I followed Linux which seems to correctly extract
  version numbers from response descriptors.
o Firmware image is no longer downloaded in device attach time. Now
  it is reloaded whenever if_init is invoked. This is to ensure
  correct operation of hardware when something goes wrong.
  Previously the controller always run without regard to running
  state of firmware. This change will add additional controller
  initialization time but it give more robust operation as txp(4)
  always start off from a known state. The controller is put into
  sleep state until administrator explicitly up the interface.
o As firmware is loaded in if_init handler, it's now possible to
  implement real watchdog timeout handler. When watchdog timer is
  expired, full-reset the controller and initialize the hardware
  again as most other drivers do. While I'm here use our own timer
  for watchdog instead of using if_watchdog/if_timer interface.
o Instead of masking specific interrupts with TXP_IMR register,
  program TXP_IER register with the interrupts to be raised and
  use TXP_IMR to toggle interrupt generation.
o Implemented txp_wait() to wait a specific state of a controller.
o Separate boot related code from txp_download_fw() and name it
  txp_boot() to handle boot process.
o Added bus_barrier(9) to host to ARM communication.
o Added endianness to all typhoon command processing. The ARM93C
  always expects little-endian format of command/data.
o Removed __STRICT_ALIGNMENT which is not valid on FreeBSD.
  __NO_STRICT_ALIGNMENT is provided for that purpose on FreeBSD.
  Previously __STRICT_ALIGNMENT was unconditionally defined for
  all architectures.
o Rewrote SIOCSIFCAP ioctl handler such that each capability can be
  controlled by ifconfig(8). Note, disabling VLAN hardware tagging
  has no effect due to the bug of firmware.
o Don't send TXP_CMD_CLEAR_STATISTICS to clear MAC statistics in
  txp_tick(). The command is not atomic. Instead, just read the
  statistics and reflect saved statistics to the statistics.
  dev.txp.%d.stats sysctl node provides detailed MAC statistics.
  This also reduces a lot of waste of CPU cycles as processing a
  command ring takes a very long time on ARM93C. Note, Rx
  multicast and broadcast statistics does not seem to right. It
  might be another bug of firmware.
o Implemented link state change handling in txp_tick(). Now sending
  packets is allowed only after establishing a valid link. Also
  invoke link state change notification whenever its state is
  changed so pseudo drivers like lagg(4) that relies on link state
  can work with failover or link aggregation without hacks.
  if_baudrate is updated to resolved speed so SNMP agents can get
  correct bandwidth parameters.
o Overhauled Tx routine such that it now honors number of allowable
  DMA segments and checks for 4 free descriptors before trying to
  send a frame. A frame may require  4 descriptors(1 frame
  descriptor, 1 or more frame descriptors, 1 TSO option descriptor,
  one free descriptor to prevent descriptor wrap-around) at least
  so it's necessary to check available free descriptors prior to
  setting up DMA operation.
o Added a sysctl variable dev.txp.%d.process_limit to control
  how many received frames should be served in Rx handler. Valid
  ranges are 16 to 128(default 64) in unit of frames.
o Added ALTQ(4) support.
o Added missing IFCAP_VLAN_HWCSUM as txp(4) can offload checksum
  calculation as well as VLAN tag insertion/stripping.
o Fixed media header length for VLAN.
o Don't set if_mtu in device attach, it's already set in
  ether_ifattach().
o Enabled MWI.
o Fixed module unload panic when bpf listeners are active.
o Rearranged ethernet address programming logic such that it works
   on strict-alignment architectures.
o Removed unused member variables in softc.
o Added support for WOL.
o Removed now unused TXP_PCI_LOMEM/TXP_PCI_LOIO.
o Added wakeup command TXP_BOOTCMD_WAKEUP definition.
o Added a new firmware version query command, TXP_CMD_READ_VERSION.
o Removed volatile keyword in softc as bus_dmamap_sync(9) should
  take care of this.
o Removed embedded union trick of a structure used to to access
  a pointer on LP64 systems.
o Added a few TSO related definitions for struct txp_tcpseg_desc.
  However TSO is not used at all due to the limitation of hardware.
o Redefined PKT_MAX_PKTLEN to theoretical maximum size of a frame.
o Switched from bus_space_{read|write}_4 to bus_{read|write}_4.
o Added a new macro TXP_DESC_INC to compute next descriptor index.

If these drivers are setting M_VLANTAG because they are stripping the

Move ethernet VLAN tags from mtags to its own mbuf packet header field
m_pkthdr.ether_vlan.  The presence of the M_VLANTAG flag on the mbuf
signifies the presence and validity of its content.

Drivers that support hardware VLAN tag stripping fill in the received
VLAN tag (containing both vlan and priority information) into the
ether_vtag mbuf packet header field:

	m->m_pkthdr.ether_vtag = vlan_id;	/* ntohs()? */
	m->m_flags |= M_VLANTAG;

to mark the packet m with the specified VLAN tag.

On output the driver should check the mbuf for the M_VLANTAG flag to
see if a VLAN tag is present and valid:

	if (m->m_flags & M_VLANTAG) {
		... = m->m_pkthdr.ether_vtag;	/* htons()? */
		... pass tag to hardware ...
	}

VLAN tags are stored in host byte order.  Byte swapping may be necessary.

(Note: This driver conversion was mechanic and did not add or remove any
byte swapping in the drivers.)

Remove zone_mtag_vlan UMA zone and MTAG_VLAN definition.  No more tag
memory allocation have to be done.

- Store pointer to the link-level address right in "struct ifnet"
  rather than in ifindex_table[]; all (except one) accesses are
  through ifp anyway.  IF_LLADDR() works faster, and all (except
  one) ifaddr_byindex() users were converted to use ifp->if_addr.

- Stop storing a (pointer to) Ethernet address in "struct arpcom",
  and drop the IFP2ENADDR() macro; all users have been converted
  to use IF_LLADDR() instead.

Remove call to txp_set_filter() from txp_attach(). txp_set_filter() needs
the ifp, so you can't call it before doing if_alloc(). Also, there's
really no need to call it here anyway: the code I originally ported from
OpenBSD incorrectly set the station address only once at device attach
time, instead of setting in txp_init(). This meant you couldn't change
the address with ifconfig txp0 ether xx:xx:xx:xx:xx:xx. I added the
call to txp_set_filter() in txp_init() to correct this, but forgot to
remove the call from txp_attach(). Until now, it never mattered.

With this fix, the txp driver tests good:

txp0: <3Com 3cR990-TX-97 Etherlink with 3XP Processor> port 0xb800-0xb87f mem 0xe6800000-0xe683ffff irq 12 at device 10.0 on pci0
txp0: Ethernet address: 00:01:03:d4:91:4f

- Add locking and mark MPSAFE.  The driver had a mutex in the softc and
  even initialized it, but it never used it.
- Use callout_*() to manage the callout.
- Use m_devget() to copy data out of the rx buffers rather than doing it
  all by hand.
- Use m_getcl() to allocate mbuf clusters rather than doing it all by hand.
- Don't free the software descriptor for a rx ring entry if we can't
  allocate an mbuf cluster for it.  We left a dangling pointer and never
  reallocated the entry anyway.  OpenBSD's code (from which this was
  derived) has the same bug.

Make sure that we call if_free(ifp) after bus_teardown_intr.  Since we
could get an interrupt after we free the ifp, and the interrupt
handler depended on the ifp being still alive, this could, in theory,
cause a crash.  Eliminate this possibility by moving the if_free to
after the bus_teardown_intr() call.

Stop embedding struct ifnet at the top of driver softcs. Instead the
struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.

This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.

Other changes of note:
 - Struct arpcom is no longer referenced in normal interface code.
   Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
   To enforce this ac_enaddr has been renamed to _ac_enaddr.
 - The second argument to ether_ifattach is now always the mac address
   from driver private storage rather than sometimes being ac_enaddr.

All current uses of pci_set_powerstate are bogus, at least in theory.
However, they are presently necessary due to bigger bogusness in the
pci bus layer not doing the right thing on suspend/resume or on
initial device probe.  This is exactly the sort of thing that the
BURN_BRIDGES option was invented for.  Mark all of them as
BURN_BRIDGES.  As soon as I have the powerstate stuff properly
integrated into the pci bus code, I intend to remove all these
workarounds.

Re-order things slightly in the RX handler for VLAN support: we need
call vlan_input_tag() after stripping the ether header from the frame
with m_adj(), not before.

You were knocked senseless by the Boomerang, spun around by the Cyclone,
blown over by the Hurricane and had a house dropped on you by the Tornado.
Now it's time to have your parade rained on by... the Typhoon!

This commit adds driver support for 3Com 3cR990 10/100 ethernet
adapters based on the Typhoon I and Typhoon II chipsets. This is actually
a port of the OpenBSD driver with many hacks by me.

No Virginia, there isn't any support for the hardware crypto yet. However
there is support for TCP/IP checksum offload and VLANs.

Special thanks go to Jason Wright, Aaron Campbell and Theo de Raadt for
squeezing enough info out of 3Com to get this written, and for doing
most of the hard work.

Manual page is included. Compiled as a module and included in GENERIC.
