/*
 * 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 is a very close 21140A clone.  It has GPR
 *	  and MII media, and a GPIO facility, and uses the ISV
 *	  SROM format (or, at least, should, because of the GPIO
 *	  facility).  The 98713A has MII, no GPIO facility, and
 *	  an internal NWay block.  The 98715, 98715A, and 98725
 *	  have only GPR media and the NWay block.  The 98715,
 *	  98715A, and 98725 support power management.
 *
 *	- Lite-On 82C115 (PNIC II):
 *
 *	  A clone of the Macronix MX98725, with the following differences:
 *
 *		- Wake-On-LAN support
 *		- 128-bit multicast hash table rather than the
 *		  standard 512-bit hash table
 *		- 802.3x flow control
 *
 *	- Lite-On 82C168, 82C169 (PNIC):
 *
 *	  Pretty close, with only a few minor differences:
 *
 *		- EEPROM is accessed completely differently.
 *		- MII is accessed completely differently.
 *		- No SIO facility (due to the above two differences).
 *		- GPIO interface is different than the 21140's.
 *		- Boards that lack PHYs use the internal NWay block
 *		  and transciever.
 *
 *	- Winbond 89C840F
 *
 *	  Less similar, but still roughly compatible (enough so
 *	  that the driver can be adapted, at least):
 *
 *		- Registers lack the pad word between them.
 *		- Instead of a setup frame, there are two station
 *		  address registers and two multicast hash table
 *		  registers (64-bit multicast hash table).
 *		- Only supported media interface is MII-over-SIO.
 *		- Different OPMODE register bits for various things
 *		  (mostly media related).
 *
 *	- ADMtek AL981
 *
 *	  Another pretty-close clone:
 *
 *		- Wake-On-LAN support
 *		- Instead of a setup frame, there are two station
 *		  address registers and two multicast hash table
 *		  registers (64-bit multicast hash table).
 *		- 802.3x flow control
 *		- Only supported media interface is built-in PHY
 *		  which is accessed through a set of special registers.
 *		- Not all registers have the pad word between them,
 *		  but luckily, there are all AL981-specific registers,
 *		  so this is easy to deal with.
 *
 * Some of the clone chips have different registers, and some have
 * different bits in the same registers.  These will be denoted by
 * PMAC, PNICII, PNIC, WINB, and ADM 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.
