Thanks Mike. In line with your points, I was able to work around this issue on
all my other servers with 12.4-RELEASE by removing the use of vlan and just
running straight igb. So there is something about vlan combined with these
if_em driver changes that is causing my issues here.

Unfortunately on this particular server, I am port-limited and require some
redundancy, hence the need to have the igb + lagg + vlan combination work. And
in case anyone wonders, no I did not try igb + lagg without vlan because that
would make my port limitation even worse than just going straight igb like I
did on all the other servers (which have 4-6 igb ports each).
