DESCRIPTION
Thecue driver provides support for USB Ethernet
adapters based on the Computer Access Technology Corporation's USB-EL1210A
chipset.
The USB-EL1210A supports a 512-bit multicast hash filter, single perfect filter entry for the station address and promiscuous mode. Packets are received and transmitted over separate USB bulk transfer endpoints.
The CATC chipset supports only 10Mbps half-duplex mode, hence there are no ifmedia(4) modes to select.
