NAME
fatm
- device driver for Fore PCA200E ATM interfaces
SYNOPSIS
device fatmdevice utopiadevice atm
options NATM
DESCRIPTION
The
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.fatm N .stats
Returns a device specific statistic list of
Vt uint32_t
statistic counters.
hw.atm.fatm N .istats
Returns a list of
Vt uint32_t
with internal driver statistics.
hw.atm.fatm N .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.fatm N .debug
Bf Em
(Only if debugging enabled.)
Ef 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
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.
