3226 * Each ring the host uses to post buffers to the chip is described
3227 * by a TG3_BDINFO entry in the chips SRAM area. When a packet arrives,
3228 * it is first placed into the on-chip ram. When the packet's length
3229 * is known, it walks down the TG3_BDINFO entries to select the ring.
3230 * Each TG3_BDINFO specifies a MAXLEN field and the first TG3_BDINFO
3231 * which is within the range of the new packet's length is chosen.

3233 * The "separate ring for rx status" scheme may sound queer, but it makes

3238 * eviction could occur since both entities want it in an exclusive state.
