FATM(4)			 BSD 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	inter-
     face cards.  The driver interfaces	with the natm(4) framework,
     netgraph(4) and HARP.  It provides	only PVC services.  Signalling,	AT-
     MARP, 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
     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.
