Subject: aoe: copy fallback timing information on destination failover
commit f3b8e07af7744cbb ("aoe: commands in retransmit queue use new
destination on failure") omits the copying of the coarse-grained time when
an AoE command was sent during the failover from one destination MAC
address on the AoE target to another.
The coarse-grained timing is only used when the system time changes or an
unlikely length of time has passed since the sending of the AoE command.
Users will not be impacted unless their system clock is very inaccurate or
something unusual (e.g., 10 GbE link reset) happens during the period when
the aoe driver is handling the failure of a port on the AoE target. Being
effected will mean that an AoE target could be considered "down" too
eagerly.
