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 periph-
erals, 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 sta-
tion 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
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).
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.
