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).

DIAGNOSTICS

aue%d: watchdog timeout

A packet was queued for transmission and a transmit command was issued, however the device failed to acknowledge the transmission before a timeout expired.

aue%d: no memory for rx list

The driver failed to allocate an mbuf for the receiver ring.
