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 sup-
     ported 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
