In general: you for running an experimental feature;-)

Seriously, flowtable has a number of different problems:
1) you will leak neighbor entries still
2) I have patches for VIMAGE but if you are running VIMAGE you are
    advised not to run flowtable.
3) FLOWTABLE should go from GENERIC but that's a different story.

I think net@ would have been a better initial place but since this
seems to be a problem when interacting with VIMAGE
freebsd-virtualization might be better.

What you could try is:
