     fatm -- Device driver for Fore PCA200E ATM interfaces

SYNOPSIS    [Toc]    [Back]

     device fatm
     device utopia
     device atm
     options NATM

DESCRIPTION    [Toc]    [Back]

     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) ).

BUGS    [Toc]    [Back]

     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.
