# DESCRIPTION

The `aue` driver provides support for USB Ethernet adapters based on the ADMtek AN986 Pegasus and AN8511 Pegasus II chipsets.

The Pegasus contains a 10/100 Ethernet MAC with MII interface and is designed to work with both Ethernet and HomePNA transceivers. Although designed to interface with 100Mbps peripherals, the existing USB standard specifies a maximum transfer speed of 12Mbps. Users should therefore not expect to actually achieve 100Mbps speeds with these devices.

The Pegasus supports a 64-bit multicast hash table, single perfect filter entry for the station address and promiscuous mode. Packets are received and transmitted over separate USB bulk transfer endpoints.

The `aue` driver supports the following media types:

autoselect
  Enable automatic selection of the media type and options. The user can manually override the automatically selected mode by adding media options to the /etc/rc.conf file.
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.

The `aue` 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).
