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) frame
- work,
netgraph(4) and HARP. It provides only PVC services. Sig - nalling,
ATMARP, ILMI and other higher layer protocols are implement - ed using
netgraph(4) or HARP. - For configuring the card for IP see natmip(4). The follow
- ing 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 in
- terface's send
queue when the cards transmit queue is found to be - full. They
are transmitted later. If this is not set the pack - ets 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)).

BUGS
- These cards can CBR shape a single VCC only. It is current
- ly possible to
request more than one CBR connection. In this case all the - timing will
be wrong. See hatm(4) for a better card. - BSD May 15, 2003
