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:
-
FORE AAL 0: The cell service;
-
FORE AAL 4: Version three and four of AAL;
-
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:
