36 * CATC USB-EL1210A USB to ethernet driver. Used in the CATC Netmate
37 * adapters and others.

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