I think some bridge or vlan scenarios require promiscuous mode (and the
corresponding disabling of hardware acceleration). Maybe the real issue is that
something accidentally disabled it and you now only work when tcpdump
re-enables it. I'm not sure how this is supposed to be managed atomically when
multiple programs may manipulate it and it needs to be propagated across
multiple bonded nics, but maybe something went wrong there. At least some
things log the change so maybe you can get a hint about when it was turned on
and off.
