[PATCH] tg3: fix ASF heartbeat
Change the ASF heart beat to 5 seconds for faster detection of system crash. The driver sends the heartbeat every 2 seconds and the ASF firmware will timeout and reset the device if no heartbeat is received after 5 seconds. The old scheme of 2 minutes is ineffective. tg3_write_mem_fast() is added to speed up the IO to send the heartbeat. When no workaround is needed, it will use direct MMIO to memory space to write to memory. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
