* 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.

|
|
* 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.
