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) 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)).

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.
