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

* 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.
