HFA(4)							   BSD Kernel Interfaces Manual 						    HFA(4)

NAME

     hfa -- FORE Systems 200-Series ATM adapter driver

SYNOPSIS

     device hfa

DESCRIPTION

     The hfa driver provides support for the FORE Systems ATM series 200 adapters.  This driver will support up to eight devices in a system at
     any given time.  The hfa driver follows the AALI or FORE ATM Adaptation Layer Interface and as such will adhere to its specifications.  The
     supported AALs include:

     o	 FORE AAL 0: The cell service;

     o	 FORE AAL 4: Version three and four of AAL;

     o	 FORE AAL 5: Version five of AAL.

     The hfa driver supports traffic shaping for cards with firmware revisions of 4.X.X, see fore_dnld(8).  The following sysctls are recognized
     by the driver and may be used to enable or disable traffic shaping:

     hw.atm.hfaN.shape (0)
	     Disable shaping on card number N.

     hw.atm.hfaN.shape (1)
	     Set one VCI to be traffic shaped on device N.  This will shape the first CBR VCI which is opened.

     hw.atm.hfaN.shape (2)
	     Attempt to shape all VCIs on device N.
     The firmware should be loaded before using this driver, this can be an easy task if the fore_dnld(8) utility is used.  If the /etc/rc.d/atm1
     file has been properly configured then the firmware update should be automatic.

HARDWARE

     The hfa driver supports the following adapters:

     o	 FORE Systems PCA-200E ATM
     o	 FORE Systems 200S
     o	 FORE Systems 200

DIAGNOSTICS

     fore_cmd_drain: %s%d: GET_PROM failed  The driver failed to drain the PROM buffer.

     fore initialization failed: intf=%s%d  Initialization of the card has failed.

     fore initialization timed out: intf=%s%d  Initialization of the card has timed out.

     hfa: version mismatch: fore=%d.%d kernel=%d.%d  A version mismatch error has occurred.
