3304 * Each ring the host uses to post buffers to the chip is described
3305 * by a TG3_BDINFO entry in the chips SRAM area. When a packet arrives,
3306 * it is first placed into the on-chip ram. When the packet's length
3307 * is known, it walks down the TG3_BDINFO entries to select the ring.
3308 * Each TG3_BDINFO specifies a MAXLEN field and the first TG3_BDINFO
3309 * which is within the range of the new packet's length is chosen.
3310 *
3311 * The "separate ring for rx status" scheme may sound queer, but it makes
3312 * sense from a cache coherency perspective. If only the host writes
3313 * to the buffer post rings, and only the chip writes to the rx status
3314 * rings, then cache lines never move beyond shared-modified state.
