/*
 * 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.
