    /*
     * 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
    *      
    *        21433 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.

    *      ---     ---     -----------
    *      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.
