|
.Sh NAME
|
|
.Nm arswitch
|
|
.Nd driver for Atheros Fast Ethernet switch
|
|
.Sh SYNOPSIS
|
|
.Cd "device mdio"
|
|
.Cd "device etherswitch"
|
|
.Cd "device arswitch"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
device driver provides a management interface to multiple Atheros
|
|
fast ethernet switch chips:
|
|
.Bl -tag -compact -width "AR7240"
|
|
.It AR7240
|
|
Wireless Network Processor SOC with five Fast Ethernet PHYs
|
|
.It AR8216
|
|
Fast Ethernet Switch
|
|
.It AR8226
|
|
.It AR8316
|
|
Six-port Gigabit Ethernet Switch
|
|
.It AR8327
|
|
Seven-port Gigabit Ethernet Switch
|
|
.It AR9340
|
|
Wireless networking SoC
|
|
.El
|
|
.Pp
|
|
The driver uses an
|
|
.Xr mdio 4
|
|
or
|
|
.Xr miibus 4
|
|
interface to configure the ethernet interface.
|
|
.Pp
|
|
This driver supports port based vlan, and
|
|
IEEE 802.1Q (QinQ).
|
|
These options can be configured with the
|
|
.Xr etherswitchcfg 8
|
|
command.
|
|
.Nm
|
|
supports
|
|
.Dv addtag ,
|
|
.Dv striptag ,
|
|
and
|
|
.Dv doubletag .
|
|
.Dv addtag
|
|
and
|
|
.Dv striptag
|
|
are mutually exclusive.
|
|
.Pp
|
|
Setting the switch MAC address is not supported.
