if_em VLAN interfaces wont pass traffic after reboot
Post the merge of the remote-tracking branch 'origin/stable/12' into devel-12 on Jun 12th. if_em0 interfaces wont pass VLAN traffic after a reboot.
If you ifconfig down and up the parent interface they will often come back online.
I believe it is related to the following bug.
