NAME

     en -- device driver for Midway-based ATM interfaces

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

	   device en
	   device atm
	   device utopia

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   if_en_load="YES"

DESCRIPTION

     The en device driver supports Midway-based ATM interfaces including the Efficient Networks, Inc. ENI-155 and Adaptec ANA-59x0.  Midway is an
     AAL5 SAR (Segmentation and Reassembly) chip.

     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.enX.istats
	     Contains an array of uint32_t with internal driver statistics.

     hw.atm.enX.debug
	     This is a bit map of debugging options.  This variable is only available when the driver is compiled with debugging support.

     The driver supports the media options sdh, noscramb and unassigned (see utopia(4)).

DIAGNOSTICS

     en0 <Efficient Networks ENI-155p> rev 0 int a irq 5 on pci0:16
     en0: ATM midway v0, board IDs 6.0, Utopia (pipelined), 512KB on-board RAM
     en0: maximum DMA burst length = 64 bytes
     en0: 7 32KB receive buffers, 8 32KB transmit buffers allocated

CAVEATS

     The driver extensively uses DMA on PCI.  The first generation PCI chipsets do not work or exhibit poor performance.

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)).

DIAGNOSTICS

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.
