/*
 * The Tulip filter is programmed by "transmitting" a Setup Packet
 * (indicated by TDCTL_Tx_SET).  The filtering type is indicated
 * as follows:
 *
 *      FT1     FT0     Description
 *      ---     ---     -----------
 *      0       0       Perfect Filtering: The Tulip interprets the
 *                      descriptor buffer as a table of 16 MAC addresses
 *                      that the Tulip should receive.
 *
 *      0       1       Hash Filtering: The Tulip interprets the
 *                      descriptor buffer as a 512-bit hash table
 *                      plus one perfect address.  If the incoming
 *                      address is Multicast, the hash table filters
 *                      the address, else the address is filtered by
 *                      the perfect address.
 *
 *      1       0       Inverse Filtering: Like Perfect Filtering, except
 *                      the table is addresses that the Tulip does NOT
 *                      receive.
 *
 *      1       1       Hash-only Filtering: Like Hash Filtering, but
 *                      physical addresses are matched by the hash table
 *                      as well, and not by matching a single perfect
 *                      address.
 *
 * A Setup Packet must always be 192 bytes long.  The Tulip can store
 * 16 MAC addresses.  If not all 16 are specified in Perfect Filtering
 * or Inverse Filtering mode,  then unused entries should duplicate
 * one of the valid entries.
