Description of problem:
Starting at kernel 4.16.0, KVM guests using VLANs are no longer able to communicate
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Update from 4.15-rc9 to 4.16
VLAN tags seems to be dropped
VLAN communication shouldn't be dropped
I've reproduced this with 4.17.0 too so this issue has been around for a while.
