44 * Register description for the Digital Semiconductor ``Tulip'' (21x4x)
45 * Ethernet controller family, and a variety of clone chips, including:
46 *
47 * - Macronix 98713, 98713A, 98715, 98715A, 98725 (PMAC):
48 *
49 * These chips are fairly straight-forward Tulip clones.
50 * The 98713 and 98713A have an MII. All have an internal
51 * transciever capable of NWAY. The 98713A, 98715A, and
52 * 98725 support power management.
53 *
54 * - Lite-On 82C168, 82C169 (PNIC):
55 *
56 * These are Tulip clones with a few small differences; the
57 * EEPROM is accessed totally differently, as is the MII.
58 * The PNIC also has a built-in NWAY transciever.
59 *
60 * - Winbond 89C840F
61 *
62 * Fairly straight-forward Tulip clone, with the exception
63 * that registers don't have a pad longword between them,
64 * and the receive filter is set up differently: instead of
65 * a setup packet, we have 2 32-bit multicast hash table
66 * registers, and 2 station address registers.
67 *
68 * Some of the clone chips have different registers, and some have
69 * different bits in the same registers. These will be denoted by
70 * PMAC, PNIC, and WINB in the register/bit names.

165 *
166 * FT1 FT0 Description
167 * --- --- -----------
168 * 0 0 Perfect Filtering: The Tulip interprets the
169 * descriptor buffer as a table of 16 MAC addresses
170 * that the Tulip should receive.
171 *
172 * 0 1 Hash Filtering: The Tulip interprets the
173 * descriptor buffer as a 512-bit hash table
174 * plus one perfect address. If the incoming
175 * address is Multicast, the hash table filters
176 * the address, else the address is filtered by
177 * the perfect address.
178 *
179 * 1 0 Inverse Filtering: Like Perfect Filtering, except
180 * the table is addresses that the Tulip does NOT
181 * receive.
182 *
183 * 1 1 Hash-only Filtering: Like Hash Filtering, but
184 * physical addresses are matched by the hash table
185 * as well, and not by matching a single perfect
186 * address.
187 *
188 * A Setup Packet must always be 192 bytes long. The Tulip can store
189 * 16 MAC addresses. If not all 16 are specified in Perfect Filtering
190 * or Inverse Filtering mode, then unused entries should duplicate
191 * one of the valid entries.
