--- Comment #1 from Joshua Kinard <freebsd@kumba.dev> ---
This was also discussed on Reddit in r/FreeBSD a few months ago:
https://new.reddit.com/r/freebsd/comments/1bfvof2/em0_disconnects_when_added_toremoved_from_bridge/

Consensus there was that the problem was "solved" by disabling RX/TX checksum
offloading on the interface, but I don't know if anyone noticed that modifying
the bridge membership was re-enabling txcsum/txcsum6 on em(4).
