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
	     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
	     src/sys/dev/fatm/if_fatmvar.h for the possible flags.

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

DIAGNOSTICS

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.
