I changed the default using `default-vlan-id 4095` for that very
reason. Perhaps this is still a default vid related bug. I'll see if I can
reproduce this with some other vid.

The brocade docs list the reserved vlans (4091, 4092) explicitly and allow
to change them like the default vid. The 4095 default vid I'm using is the
example they use in the docs so I'd be surprised if that's broken.

Using such low vlan ids is a holdover from using some ath9k wifi APs that
only supported 4-bit vids so we had to make every number count ;) I'll
definetly reconsider that in the future haha.

Thanks,
