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 inter-
     face 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 coun-
	  ters.

     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_fatm-
	  var.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.
