40 * adapters and others.

48 * The CATC USB-EL1210A provides USB ethernet support at 10Mbps. The
49 * RX filter uses a 512-bit multicast hash table, single perfect entry
50 * for the station address, and promiscuous mode. Unlike the ADMtek
51 * and KLSI chips, the CATC ASIC supports read and write combining
52 * mode where multiple packets can be transfered using a single bulk
53 * transaction, which helps performance a great deal.
