Subject: [net-next 10/18] fm10k: allow creation of VLAN interfaces even while down

From: Jacob Keller <jacob.e.keller@...el.com>

We re-sync upon going up, so there is little reason to worry about not
syncing immediately with switch. This prevents an error that occurs if
you add a VLAN interface while down.
