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. .El .Pp The driver supports the media options .Cm sdh , noscramb and .Cm unassigned (see .Xr utopia 4 ) . .Sh DIAGNOSTICS .Bd -literal fatm0: <FORE PCA200E> mem 0xd5800000-0xd59fffff irq 9 at device 9.0 on pci0 .Ed .Sh SEE ALSO .Xr natm 4 , .Xr natmip 4 , .Xr utopia 4 .Sh AUTHORS .An Harti Brandt Aq harti@FreeBSD.org .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.
