3275 * descriptor as provided by the host, updates the status and length

3277 *
3278 * Each ring the host uses to post buffers to the chip is described
3279 * by a TG3_BDINFO entry in the chips SRAM area. When a packet arrives,
3280 * it is first placed into the on-chip ram. When the packet's length
3281 * is known, it walks down the TG3_BDINFO entries to select the ring.
3282 * Each TG3_BDINFO specifies a MAXLEN field and the first TG3_BDINFO
3283 * which is within the range of the new packet's length is chosen.
3284 *
3285 * The "separate ring for rx status" scheme may sound queer, but it makes
3286 * sense from a cache coherency perspective. If only the host writes
3287 * to the buffer post rings, and only the chip writes to the rx status
3288 * rings, then cache lines never move beyond shared-modified state.
3289 * If both the host and chip were to write into the same ring, cache line
3290 * eviction could occur since both entities want it in an exclusive state.
