4415 *
4416 * Each ring the host uses to post buffers to the chip is described
4417 * by a TG3_BDINFO entry in the chips SRAM area. When a packet arrives,
4418 * it is first placed into the on-chip ram. When the packet's length
4419 * is known, it walks down the TG3_BDINFO entries to select the ring.
4420 * Each TG3_BDINFO specifies a MAXLEN field and the first TG3_BDINFO
4421 * which is within the range of the new packet's length is chosen.
4422 *
4423 * The "separate ring for rx status" scheme may sound queer, but it makes
