Add module version to iwi/ipw/wpi and iwn.

The version is used to check if a module is already preset, not setting
it results in:

can't re-use a leaf (ipw)!
module_register: module pci/ipw already exists!
Module pci/ipw failed to register: 17

while trying to load the module due to an entry in loader.conf. With this
commit we get the expected:

module ipw already present!

The firmware does pad notifications to an even number of bytes (at least
the association notification), the included information though always
contains an elem block with an odd number of bytes. We handle the last
byte as if it might contain a whole elem block, this of course is not
true as one byte is not enough to hold a block, we therefore discard the
complete frame. The solution here is to subtract one from the actual
notification length, this is also what the Linux driver does. With this
change the frame ends exactly where the last elem block ends.

Instead of calling return when reaching the end of the assoc notification
break the loop instead. We want to run the code after the while loop
to set an associd and capinfo. If we don't do this net80211 will drop
frames because it assumes the node has not yet been associated.

SVN rev 213734 on 2010-10-12 17:12:35Z by bschmidt

When bringing the interface down we clear the command queue but do
not reset the sc_cmd_cur and sc_cmd_next indices. If there are
still pending commands while clearing the queue those two indices
are off by at least one. This leads to no commands being sent
to the firmware until the queue overruns. Fix this by also resetting
the indices.

This is a direct commit as the code does not exist in head.

Overhaul monitor mode handling:
o replace DLT_IEEE802_11 support in net80211 with DLT_IEEE802_11_RADIO
  and remove explicit bpf support from wireless drivers; drivers now
  use ieee80211_radiotap_attach to setup shared data structures that
  hold the radiotap header for each packet tx/rx
o remove rx timestamp from the rx path; it was used only by the tdma support
  for debugging and was mostly useless due to it being 32-bits and mostly
  unavailable
o track DLT_IEEE80211_RADIO bpf attachments and maintain per-vap and
  per-com state when there are active taps
o track the number of monitor mode vaps
o use bpf tap and monitor mode vap state to decide when to collect radiotap
  state and dispatch frames; drivers no longer explicitly directly check
  bpf state or use bpf calls to tap frames
o handle radiotap state updates on channel change in net80211; drivers
  should not do this (unless they bypass net80211 which is almost always
  a mistake)
o update various drivers to be more consistent/correct in handling radiotap
o update ral to include TSF in radiotap'd frames
o add promisc mode callback to wi

Create a taskqueue for each wireless interface which provides a serialised
sleepable context for net80211 driver callbacks. This removes the need for USB
and firmware based drivers to roll their own code to defer the chip programming
for state changes, scan requests, channel changes and mcast/promisc updates.
When a driver callback completes the hardware state is now guaranteed to have
been updated and is in sync with net80211 layer.

This nukes around 1300 lines of code from the wireless device drivers making
them more readable and less race prone.

The net80211 layer has been updated as follows
 - all state/channel changes are serialised on the taskqueue.
 - ieee80211_new_state() always queues and can now be called from any context
 - scanning runs from a single taskq function and executes to completion. driver
   callbacks are synchronous so the channel, phy mode and rx filters are
   guaranteed to be set in hardware before probe request frames are
   transmitted.

Hoist 802.11 encapsulation up into net80211:
o call ieee80211_encap in ieee80211_start so frames passed down to drivers
  are already encapsulated
o remove ieee80211_encap calls in drivers
o fixup wi so it recreates the 802.3 head it requires from the 802.11
  header contents
o move fast-frame aggregation from ath to net80211 (conditional on
  IEEE80211_SUPPORT_SUPERG):
  - aggregation is now done in ieee80211_start; it is enabled when the
    packets/sec exceeds ieee80211_ffppsmin (net.wlan.ffppsmin) and frames
    are held on a staging queue according to ieee80211_ffagemax
    (net.wlan.ffagemax) to wait for a frame to combine with
  - drivers must call back to age/flush the staging queue (ath does this
    on tx done, at swba, and on rx according to the state of the tx queues
    and/or the contents of the staging queue)
  - remove fast-frame-related data structures from ath
  - add ieee80211_ff_node_init and ieee80211_ff_node_cleanup to handle
    per-node fast-frames state (we reuse 11n tx ampdu state)
o change ieee80211_encap calling convention to include an explicit vap
  so frames coming through a WDS vap are recognized w/o setting M_WDS

With these changes any device able to tx/rx 3Kbyte+ frames can use fast-frames.

Eliminate ic_myaddr so changing the mac address of a device works correctly:
o remove ic_myaddr from ieee80211com
o change ieee80211_ifattach to take the mac address of the physical device
  and use that to setup the lladdr.
o replace all references to ic_myaddr in drivers by IF_LLADDR
o related cleanups (e.g. kill dead code)

Change the calling convention for ic_node_alloc to deal with
some longstanding issues:
o pass the vap since it's now the "coin of the realm" and required
  to do things like set initial tx parameters in private node
  state for use prior to association
o pass the mac address as cards that maintain outboard station
  tables require this to create an entry (e.g. in ibss mode)
o remove the node table reference, we only have one node table
  and it's unlikely this will change so this is not needed to
  find the com structure

o move IEEE80211_C_OPMODE definition to where capabilities are defined so it's
  clear it should be kept in sync (on future additions)
o check device capabilities in clone create before trying to create a vap;
  this makes driver checks unneeded
o make error codes return on failed clone request unique
o temporarily add console printfs on clone request failures to aid in
  debugging; these will move under DIAGNOSTIC or similar before release

Update 802.11 wireless support:
o major overhaul of the way channels are handled: channels are now
  fully enumerated and uniquely identify the operating characteristics;
  these changes are visible to user applications which require changes
o make scanning support independent of the state machine to enable
  background scanning and roaming
o move scanning support into loadable modules based on the operating
  mode to enable different policies and reduce the memory footprint
  on systems w/ constrained resources
o add background scanning in station mode (no support for adhoc/ibss
  mode yet)
o significantly speedup sta mode scanning with a variety of techniques
o add roaming support when background scanning is supported; for now
  we use a simple algorithm to trigger a roam: we threshold the rssi
  and tx rate, if either drops too low we try to roam to a new ap
o add tx fragmentation support
o add first cut at 802.11n support: this code works with forthcoming
  drivers but is incomplete; it's included now to establish a baseline
  for other drivers to be developed and for user applications
o adjust max_linkhdr et. al. to reflect 802.11 requirements; this eliminates
  prepending mbufs for traffic generated locally
o add support for Atheros protocol extensions; mainly the fast frames
  encapsulation (note this can be used with any card that can tx+rx
  large frames correctly)
o add sta support for ap's that beacon both WPA1+2 support
o change all data types from bsd-style to posix-style
o propagate noise floor data from drivers to net80211 and on to user apps
o correct various issues in the sta mode state machine related to handling
  authentication and association failures
o enable the addition of sta mode power save support for drivers that need
  net80211 support (not in this commit)
o remove old WI compatibility ioctls (wicontrol is officially dead)
o change the data structures returned for get sta info and get scan
  results so future additions will not break user apps
o fixed tx rate is now maintained internally as an ieee rate and not an
  index into the rate set; this needs to be extended to deal with
  multi-mode operation
o add extended channel specifications to radiotap to enable 11n sniffing

Drivers:
o ath: add support for bg scanning, tx fragmentation, fast frames,
       dynamic turbo (lightly tested), 11n (sniffing only and needs
       new hal)
o awi: compile tested only
o ndis: lightly tested
o ipw: lightly tested
o iwi: add support for bg scanning (well tested but may have some
       rough edges)
o ral, ural, rum: add suppoort for bg scanning, calibrate rssi data

Fix an off-by-one error in iwi_init_fw_dma().  It didn't reuse the existing
DMA memory for a firmware load if it was the exact size needed, thus in the
common case the driver was constantly free'ing and reallocating the DMA
buffer and it would eventually begin to fail.  With this fix, iwi0 reuses
the same buffer the entire time and no longer fails to load the firmware
after the machine has been up for a while.

MFC: sync firmware(9) and iwi(4) with the version in HEAD (the changes
are related and this is why the MFC is done together).
In detail:

firmware(9):
  Cleanup and document the implementation of firmware(9) based on
  a version that i posted earlier on the -current mailing list,
  and subsequent feedback received. See the commit log
	luigi       2007-02-15 17:21:31 UTC
  The core of the change is just in sys/firmware.h and kern/subr_firmware.c,
  while other files are just adaptation of the clients to the ABI change
  (const-ification of some parameters and hiding of internal info,
  so this is fully compatible at the binary level).

  Note that in RELENG_6 sys/arm/xscale/ixp425, sys/dev/ipw and
  sys/dev/mxge do not exist or have not been updated to use firmware(9).

iwi(4)
  + add debugging code IWI_LOCK_CHECK() to print (under sysctl debug.iwi)
    missing locks;
  + make sure that iwi_ioctl() wait until the previous iwi_cmd() terminates.

Rename IWI_LOCK_ASSERT to IWI_LOCK_CHECK per Sam's suggestion,
and make it print under debug.iwi control same as other debugging stuff.

Remove the device_printf() in iwi_ioctl() and replace with this:

        /*
         * wait until pending iwi_cmd() are completed, to avoid races
         * that could cause problems.
         */
        while (sc->flags & IWI_FLAG_BUSY)
                msleep(sc, &sc->sc_mtx, 0, "iwiioctl", hz);

This at least prevents what has become an almost systematic failure for my
system, presumably due to a previous iwi_cmd() not complete yet by the
time iwi_ioctl() is called.

It has been pointed to my attention that the real problem could be
calling ieee80211_ioctl() with the lock held. If that is true,
there might still be a possibility for a race condition e.g. an
interrupt coming while the ioctl is sleeping.
Need to investigate further on what changes are required to release
the lock before calling ieee80211_ioctl

Address a few issues with the iwi driver, namely:

+ do not release the dma-ble region used for downloading firmware.
  This should fix the problems that some people were seeing, due to
  memory becoming too fragmented which prevented subsequent allocations
  of a suitable contiguous region of memory;

+ document the firmware format and usage in if_iwivar.h

+ use a loop to allocate the four tx rings, instead of replicating
  the body of the loop.

+ add debugging code IWI_LOCK_ASSERT() to detect missing locks.
  These only do a printf, and should go away once we figure out why
  the driver sometimes freezes the system due to a (yet unidentified)
  race condition.

+ add a device_printf() in iwi_ioctl() in certain conditions
  (see comment in the code).  This helps preventing the race condition
  mentioned above, and makes the system survive. This printf will
  also go away once fixing this bug is completed.

+ change iwi_getfw() to return 0 on success, 1 on error, consistently
  with other functions.

+ fix the argument of a sizeof() in iwi_get_firmware()

+ use le32toh() to access little-endian fields

+ simplify error handling in iwi_load_firmware() and iwi_init_locked()

The bugs fixed by this commit (the freezing one especially) are serious
enough to call for a quick MFC

Cleanup and document the implementation of firmware(9) based on
a version that i posted earlier on the -current mailing list,
and subsequent feedback received.

The core of the change is just in sys/firmware.h and kern/subr_firmware.c,
while other files are just adaptation of the clients to the ABI change
(const-ification of some parameters and hiding of internal info,
so this is fully compatible at the binary level).

In detail:
- reduce the amount of information exported to clients in struct firmware,
  and constify the pointer;

- internally, document and simplify the implementation of the various
  functions, and make sure error conditions are dealt with properly.

The diffs are large, but the code is really straightforward now (i hope).

Note also that there is a subtle issue with the implementation of
firmware_register(): currently, as in the previous version, we just
store a reference to the 'imagename' argument, but we should rather
copy it because there is no guarantee that this is a static string.
I realised this while testing this code, but i prefer to fix it in
a later commit -- there is no regression with respect to the past.

Note, too, that the version in RELENG_6 has various bugs including
missing locks around the module release calls, mishandling of modules
loaded by /boot/loader, and so on, so an MFC is absolutely necessary
there.  I was just postponing it until this cleanup to avoid doing
things twice.

Fix the following bpf(4) race condition which can result in a panic:

	(1) bpf peer attaches to interface netif0
	(2) Packet is received by netif0
	(3) ifp->if_bpf pointer is checked and handed off to bpf
	(4) bpf peer detaches from netif0 resulting in ifp->if_bpf being
	    initialized to NULL.
	(5) ifp->if_bpf is dereferenced by bpf machinery
	(6) Kaboom

This race condition likely explains the various different kernel panics
reported around sending SIGINT to tcpdump or dhclient processes. But really
this race can result in kernel panics anywhere you have frequent bpf attach
and detach operations with high packet per second load.

Summary of changes:

- Remove the bpf interface's "driverp" member
- When we attach bpf interfaces, we now set the ifp->if_bpf member to the
  bpf interface structure. Once this is done, ifp->if_bpf should never be
  NULL. [1]
- Introduce bpf_peers_present function, an inline operation which will do
  a lockless read bpf peer list associated with the interface. It should
  be noted that the bpf code will pickup the bpf_interface lock before adding
  or removing bpf peers. This should serialize the access to the bpf descriptor
  list, removing the race.
- Expose the bpf_if structure in bpf.h so that the bpf_peers_present function
  can use it. This also removes the struct bpf_if; hack that was there.
- Adjust all consumers of the raw if_bpf structure to use bpf_peers_present

Now what happens is:

	(1) Packet is received by netif0
	(2) Check to see if bpf descriptor list is empty
	(3) Pickup the bpf interface lock
	(4) Hand packet off to process

From the attach/detach side:

	(1) Pickup the bpf interface lock
	(2) Add/remove from bpf descriptor list

Now that we are storing the bpf interface structure with the ifnet, there is
is no need to walk the bpf interface list to locate the correct bpf interface.
We now simply look up the interface, and initialize the pointer. This has a
nice side effect of changing a bpf interface attach operation from O(N) (where
N is the number of bpf interfaces), to O(1).

[1] From now on, we can no longer check ifp->if_bpf to tell us whether or
    not we have any bpf peers that might be interested in receiving packets.

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.

  Propagate rename of IFF_OACTIVE and IFF_RUNNING to IFF_DRV_OACTIVE and
  IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to
  ifnet.if_drv_flags.  Device drivers are now responsible for
  synchronizing access to these flags, as they are in if_drv_flags.  This
  helps prevent races between the network stack and device driver in
  maintaining the interface flags field.

  Many __FreeBSD__ and __FreeBSD_version checks maintained and continued;
  some less so.

Add some necessary bits for upcoming 802.11e support:
o management of multiple tx rings (up to 4)
o setting of WME IE in association requests

Some features are still missing though, like the possibility to override
the default cwmin/cwmax/asfn values of each tx queues.

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.

o Temporarly disable 802.11a channels scanning that was causing firmware
  panics with 2915ABG adapters until I find a better fix.  This breaks
  802.11a support.
o Temporarly switch back to software WEP until I implement hardware
  encryption for AES and TKIP too.
