|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
device driver supports the FORE (now Marconi) PCA200E ATM interface cards.
|
|
The driver interfaces with the
|
|
.Xr natm 4
|
|
framework,
|
|
.Xr netgraph 4
|
|
and HARP.
|
|
It provides only PVC services.
|
|
Signalling, ATMARP, ILMI and other
|
|
higher layer protocols are implemented using
|
|
.Xr netgraph 4
|
|
or HARP.
|
|
.Pp
|
|
For configuring the card for IP see
|
|
.Xr natmip 4 .
|
|
The following sysctls are recognized by the driver additionally to those
|
|
handled by
|
|
.Xr utopia 4 :
|
|
.Bl -tag -width indent
|
|
.It Va hw.atm.fatm Ns Ar N Ns Va .stats
|
|
Returns a device specific statistic list of
|
|
.Vt uint32_t
|
|
statistic counters.
|
|
.It Va hw.atm.fatm Ns Ar N Ns Va .istats
|
|
Returns a list of
|
|
.Vt uint32_t
|
|
with internal driver statistics.
|
|
.It Va hw.atm.fatm Ns Ar N Ns Va .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.
|
|
.It Va hw.atm.fatm Ns Ar N Ns Va .debug
|
|
.Bf Em
|
|
(Only if debugging enabled.)
|
|
.Ef
|
|
These are debugging flags.
|
|
See

|
.Pa src/sys/dev/fatm/if_fatmvar.h
|
|
for the possible flags.
|

.Sh 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
|
|
.Xr hatm 4
|
|
for a better card.
