/*
* 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.
*
* The 98715AEC adds 802.3x flow Frame based Flow Control to the
* 98715A.
*
* - 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 transceiver.
*
* - 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.
*
* - ADMtek AN983 and AN985
*
* Similar to the ADMtek AL981, but with a few differences.
*
* - Xircom X3201-3
*
* CardBus 21143 clone, with a few differences:
*
* - No MicroWire SROM; Ethernet address must come
* from CIS.
* - Transmit buffers must also be 32-bit aligned.
* - The BUSMODE_SWR bit is not self-clearing.
* - Must include FS|LS in setup packet descriptor.
* - SIA is not 21143-like, and all media attachments
* are MII-on-SIO.
*
* - Davicom DM9102 and DM9102A
*
* Pretty similar to the 21140A, with a few differences:
*
* - Wake-On-LAN support
* - DM9102 has built-in 10/100 PHY on MII interface.
* - DM9102A has built-in 10/100 PHY on MII interface,
* as well as a HomePNA 1 PHY on an alternate MII
* interface (selected by clearing OPMODE_PS).
* - The chip has a bug in the transmit DMA logic,
* requiring that the packet be comprised of only
* one DMA segment.
* - The bus interface is buggy, and the BUSMODE register
* must be initialized to 0.
* - There seems to be an interrupt logic bug, requiring
* that interrupts be disabled on the chip during the
* interrupt handler.
*
* - ASIX AX88140
*
* 21143 clone with a few differences:
*
* - Specific broadcast bit in the OPMODE register.
* - Transmit buffer must be 32-bit aligned.
* - The BUSMODE_SWR bit is not self-clearing.
* - External 10BaseT PHY or 10/100 MII.
*
* 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, DM, WINB, ADM and AX in the register/bit names.

* 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.
