NAME

     harp -- pseudo physical interface driver for HARP

SYNOPSIS

     device atm
     options NATM
     options ATM_CORE
     device harp

DESCRIPTION

     The harp driver, when loaded, attaches to all netgraph(4) ATM interfaces in the system, and for each of these interfaces presents a physical
     interface to the HARP stack.  The name of the harp physical interface is the same as the name of the Netgraph interface (they are in differ-
     ent namespaces).

SEE ALSO

     fatm(4), hatm(4), ng_atm(4), patm(4), atm(8)

CAVEATS

     When fatm(4) is used, it must be started before harp is loaded, to get the correct configuration for the HARP physical interface.

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.
