.Sh NAME
.Nm hfa
.Nd FORE Systems 200-Series ATM adapter driver
.Sh SYNOPSIS
.Cd device hfa
.Sh DESCRIPTION
The
.Nm
driver provides support for the
.Tn FORE
Systems
.Tn ATM
series 200 adapters.
This driver will support up to eight devices in a system
at any given time.
The
.Nm
driver follows the
.Tn AALI
or
.Tn FORE
.Tn ATM
Adaptation Layer Interface and as such
will adhere to its specifications.
The supported
.Tn AALs
include:
.Bl -bullet
.It
FORE AAL 0:
The cell service;
.It
FORE AAL 4:
Version three and four of AAL;
.It
FORE AAL 5:
Version five of AAL.
.El
.Pp
The
.Nm
driver supports traffic shaping for cards with firmware
revisions of 4.X.X, see
.Xr fore_dnld 8 .
The following sysctls are recognized by the driver and
may be used to enable or disable traffic shaping:
.Bl -tag -width indent
.It Va hw.atm.hfa Ns Ar N Ns Va .shape Pq 0
Disable shaping on card number
.Ar N .
.It Va hw.atm.hfa Ns Ar N Ns Va .shape Pq 1
Set one VCI to be traffic shaped on device
.Ar N .
This will shape the first CBR VCI which is opened.
.It Va hw.atm.hfa Ns Ar N Ns Va .shape Pq 2
Attempt to shape all VCIs on device
.Ar N .
.El
The firmware should be loaded before using this
driver, this can be an easy task if the
.Xr fore_dnld 8
utility is used.
If the
.Pa /etc/rc.d/atm1
file has been properly configured then the firmware
update should be automatic.
.Sh HARDWARE
The following devices are currently supported:
.Pp
.Bl -bullet
.It
FORE Systems PCA-200E ATM
.It
FORE Systems 200S
.It
FORE Systems 200
