FATM(4)                FreeBSD Kernel Interfaces Manual                FATM(4)

NAME
     fatm - Device driver for Fore PCA200E ATM interfaces

SYNOPSIS
     device fatm
     device utopia
     device atm
     options NATM

DESCRIPTION
     The fatm device driver supports the FORE (now Marconi) PCA200E ATM
     interface cards.  The driver interfaces with the natm(4) framework,
     netgraph(4) and HARP.  It provides only PVC services. Signalling, ATMARP,
     ILMI and other higher layer protocols are implemented using netgraph(4)
     or HARP.

     For configuring the card for IP see natmip(4).  The following sysctls are
     recognized by the driver additionally to those handled by utopia(4):

     hw.atm.fatmN.stats
          Returns a device specific statistic list of uint32_t statistic
          counters.

     hw.atm.fatmN.istats
          Returns a list of uint32_t with internal driver statistics.

     hw.atm.fatmN.retry_tx
          If this is set packets are stuffed back into the interface's send
          queue when the cards transmit queue is found to be full. They are
          transmitted later.  If this is not set the packets are dropped. It
          may be useful to set this if only UBR traffic is sent.

     hw.atm.fatmN.debug
          (only if debugging enabled) These are debugging flags. See
          if_fatmvar.h() for the possible flags.

     The driver supports the media options sdh, noscramb and unassigned (see
     utopia(4) ).

DIAGNOSTICS
     fatm0: <FORE PCA200E> mem 0xd5800000-0xd59fffff irq 9 at device 9.0 on pci0

BUGS
     These cards can CBR shape a single VCC only. It is currently possible to
     request more than one CBR connection. In this case all the timing will be
     wrong. See hatm(4) for a better card.
