3219  * host.  The chip does not write into the original descriptor the
3220  * RX buffer was obtained from.  The chip simply takes the original
3221  * descriptor as provided by the host, updates the status and length
3222  * field, then writes this into the next status ring entry.
3223  *
3224  * Each ring the host uses to post buffers to the chip is described
3225  * by a TG3_BDINFO entry in the chips SRAM area.  When a packet arrives,
3226  * it is first placed into the on-chip ram.  When the packet's length
3227  * is known, it walks down the TG3_BDINFO entries to select the ring.
3228  * Each TG3_BDINFO specifies a MAXLEN field and the first TG3_BDINFO
3229  * which is within the range of the new packet's length is chosen.
3230  *
3231  * The "separate ring for rx status" scheme may sound queer, but it makes
3232  * sense from a cache coherency perspective.  If only the host writes
3233  * to the buffer post rings, and only the chip writes to the rx status
3234  * rings, then cache lines never move beyond shared-modified state.
3235  * If both the host and chip were to write into the same ring, cache line
3236  * eviction could occur since both entities want it in an exclusive state.
