|

|
* host. The chip does not write into the original descriptor the
|
|
* RX buffer was obtained from. The chip simply takes the original
|
|
* descriptor as provided by the host, updates the status and length
|
|
* field, then writes this into the next status ring entry.
|
|
*
|
|
* Each ring the host uses to post buffers to the chip is described
|
|
* by a TG3_BDINFO entry in the chips SRAM area. When a packet arrives,
|
|
* it is first placed into the on-chip ram. When the packet's length
|
|
* is known, it walks down the TG3_BDINFO entries to select the ring.
|
|
* Each TG3_BDINFO specifies a MAXLEN field and the first TG3_BDINFO
|
|
* which is within the range of the new packet's length is chosen.
|
|
*
|
|
* The "separate ring for rx status" scheme may sound queer, but it makes
|
|
* sense from a cache coherency perspective. If only the host writes
|
|
* to the buffer post rings, and only the chip writes to the rx status
|
|
* rings, then cache lines never move beyond shared-modified state.
|
|
* If both the host and chip were to write into the same ring, cache line
|
|
* eviction could occur since both entities want it in an exclusive state.
