# DESCRIPTION

The `axe` driver provides support for USB Ethernet adapters based on the ASIX Electronics AX88172, AX88178, AX88772, AX88772A, AX88772B USB 2.0 chipsets.

The chip contains a 10/100 Ethernet MAC with MII interface and is designed to work with both Ethernet and HomePNA transceivers. The AX88172 and AX88772 contain 10/100 Ethernet MACs with MII interfaces. The AX88178 contains a 10/100/1000 Gigabit Ethernet MAC with a GMII/MII interface. The chip also supports USB 2.0, thereby accommodating 100 Mb/s data rates.

The `axe` driver supports the following media types:

autoselect
  Enable automatic selection of the media type and options.
10baseT/UTP
  Set 10Mbps operation. The mediaopt option can also be used to enable full-duplex operation. Not specifying full duplex implies half-duplex mode.
100baseTX
  Set 100Mbps (fast Ethernet) operation. The mediaopt option can also be used to enable full-duplex operation. Not specifying full duplex implies half-duplex mode.
1000baseT
  Set 1000Mbps (Gigabit Ethernet) operation (AX88178 only).

The `axe` driver supports the following media options:

full-duplex
  Force full duplex operation. The interface will operate in half duplex mode if this media option is not specified.

For more information on configuring this device, see ifconfig(8).
