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.
