I just upgraded a machine from 10-STABLE to FreeBSD 11, and the machine
seems to crash frequently if flowtable is enabled. Other machines I have
using the identical kernel does not seem to be affected, and the same
hardward on the old 10-STABLE branch was quick stable. Interfaces on this
machine include several vlans on top of a lagg. Does anyone have any ideas
what the trouble might be?
