I think that only happens if you don't have monitor_during_oper set;
otherwise it's a bug.

I am, however, not entirely sure we should be forwarding packets with
failed CRC on hard monitor interfaces. Because if you have both a hard
monitor and a regular interface (monitor_during_oper allowed) then we
will never check the CRC on frames that enter the networking path and
can get corrupted TCP packets in etc.
