3172/* The RX ring scheme is composed of multiple rings which post fresh
3173 * buffers to the chip, and one special ring the chip uses to report
3174 * status back to the host.
3175 *
3176 * The special ring reports the status of received packets to the
3177 * host. The chip does not write into the original descriptor the
3178 * RX buffer was obtained from. The chip simply takes the original
3179 * descriptor as provided by the host, updates the status and length
3180 * field, then writes this into the next status ring entry.
3181 *
3182 * Each ring the host uses to post buffers to the chip is described
3183 * by a TG3_BDINFO entry in the chips SRAM area. When a packet arrives,
3184 * it is first placed into the on-chip ram. When the packet's length
3185 * is known, it walks down the TG3_BDINFO entries to select the ring.
3186 * Each TG3_BDINFO specifies a MAXLEN field and the first TG3_BDINFO
3187 * which is within the range of the new packet's length is chosen.
3188 *
3189 * The "separate ring for rx status" scheme may sound queer, but it makes
3190 * sense from a cache coherency perspective. If only the host writes
3191 * to the buffer post rings, and only the chip writes to the rx status
3192 * rings, then cache lines never move beyond shared-modified state.
3193 * If both the host and chip were to write into the same ring, cache line
3194 * eviction could occur since both entities want it in an exclusive state.
