To run BISTs the MC goes down in to a special mode where it will only respond to MCDI from the testing PF, and TX, RX and event queues are torn down. Other PFs get a message as it goes down to tell them it's going down. When the other PFs get this message, they check the soft status register to tell when the MC has rebooted after BIST mode and they can start recovery. [bwh: Convert the test result to 1 or -1 as for earlier NICs] Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
