/* The RX ring scheme is composed of multiple rings which post fresh

* status back to the host.
*
* The special ring reports the status of received packets to the
* 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.
