/* 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.
 * 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.
