--- Comment #15 from Colin Percival <cperciva at FreeBSD.org> ---
ENA flapping every 30 minutes is almost certainly due to the MTU being set
thanks to DHCP announcing support for jumbograms.  That particular bug is fixed
in HEAD (r333454).

AFAIK this should not cause any of the other reported issues, but it would be
good if someone who is experiencing problems can confirm that they don't happen
at 30 minute intervals.
