sfc: Fix event based MCDI completion and MC REBOOT/CMDDONE ordering issue
The mcfw *never* sends CMDDONE when rebooting. Changing this so that it always
sends CMDDONE *before* REBOOT is easy on Siena, but it's not obvious that we
could guarantee to be able to implement this on future hardware.
Given this, I'm less convinced that the protocol should be changed.
To reiterate the failure mode: The driver sees this:
issue command
receive REBOOT event
Was that reboot event sent before the command was issued, or in
response to the command? If the former then there will be a subsequent
CMDDONE event, if the latter, then there will be no CMDDONE event.
Options to resolve this are:
1. REBOOT always completes an outstanding mcdi request, and we set
the credits count to ignore a subsequent CMDDONE event with
mismatching seqno.
2. REBOOT never completes an outstanding mcdi request. If there is
no CMDDONE event then we rely on the mcdi timeout code to complete
the outstanding request, incurring a 10s delay.
I'd argue that (2) is tidier, but that incurring a 10s delay is a little
needless. Let's go with (1).
