3232/* The RX ring scheme is composed of multiple rings which post fresh
3233 * buffers to the chip, and one special ring the chip uses to report
3234 * status back to the host.
3235 *
3236 * The special ring reports the status of received packets to the
3237 * host. The chip does not write into the original descriptor the
3238 * RX buffer was obtained from. The chip simply takes the original
3239 * descriptor as provided by the host, updates the status and length
3240 * field, then writes this into the next status ring entry.
3241 *
3242 * Each ring the host uses to post buffers to the chip is described
3243 * by a TG3_BDINFO entry in the chips SRAM area. When a packet arrives,
3244 * it is first placed into the on-chip ram. When the packet's length
3245 * is known, it walks down the TG3_BDINFO entries to select the ring.
3246 * Each TG3_BDINFO specifies a MAXLEN field and the first TG3_BDINFO
3247 * which is within the range of the new packet's length is chosen.
3248 *
3249 * The "separate ring for rx status" scheme may sound queer, but it makes
3250 * sense from a cache coherency perspective. If only the host writes
3251 * to the buffer post rings, and only the chip writes to the rx status
3252 * rings, then cache lines never move beyond shared-modified state.
3253 * If both the host and chip were to write into the same ring, cache line
3254 * eviction could occur since both entities want it in an exclusive state.
