The reason for this fix is, when opening a VLAN, the current code checks if the trunk interface in also open. If it's not opened, then it will open the trunk and notify all other drivers, which the VLAN driver is one of them, and when the VLAN driver is notified it will try to sync with the opened trunk, so it will be opened again. (same for the close flow)
