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