3502/* The RX ring scheme is composed of multiple rings which post fresh

3504 * status back to the host.
3505 *
3506 * The special ring reports the status of received packets to the
3507 * host. The chip does not write into the original descriptor the
3508 * RX buffer was obtained from. The chip simply takes the original
3509 * descriptor as provided by the host, updates the status and length
3510 * field, then writes this into the next status ring entry.
3511 *
3512 * Each ring the host uses to post buffers to the chip is described
3513 * by a TG3_BDINFO entry in the chips SRAM area. When a packet arrives,
3514 * it is first placed into the on-chip ram. When the packet's length
3515 * is known, it walks down the TG3_BDINFO entries to select the ring.
3516 * Each TG3_BDINFO specifies a MAXLEN field and the first TG3_BDINFO
3517 * which is within the range of the new packet's length is chosen.
3518 *
3519 * The "separate ring for rx status" scheme may sound queer, but it makes
3520 * sense from a cache coherency perspective. If only the host writes
3521 * to the buffer post rings, and only the chip writes to the rx status
3522 * rings, then cache lines never move beyond shared-modified state.
3523 * If both the host and chip were to write into the same ring, cache line
3524 * eviction could occur since both entities want it in an exclusive state.

7299 *
7300 * The heartbeat is to tell the ASF firmware that the host
7301 * driver is still alive. In the event that the OS crashes,
7302 * ASF needs to reset the hardware to free up the FIFO space
7303 * that may be filled with rx packets destined for the host.
7304 * If the FIFO is full, ASF will no longer function properly.
7305 *
7306 * Unintended resets have been reported on real time kernels
7307 * where the timer doesn't run on time. Netpoll will also have
7308 * same problem.
7309 *
7310 * The new FWCMD_NICDRV_ALIVE3 command tells the ASF firmware
7311 * to check the ring condition when the heartbeat is expiring
7312 * before doing the reset. This will prevent most unintended
7313 * resets.
