When opening a VLAN device, vlan_open() will call netdev_open() on the trunk device. This will result in a call to netdev_notify(), which will cause vlan_notify() to call vlan_sync() on the original VLAN device, which will see that the trunk device is now open but the VLAN device apparently isn't (since it has not yet been flagged as open by netdev_open()). The upshot is a second attempt to open the VLAN device, which will result in an erroneous second call to vlan_open(). This convoluted chain of events then terminates harmlessly since vlan_open() calls netdev_open() on the trunk device, which just returns immediately since the trunk device is by now flagged as being already open. Prevent this from happening by having netdev_open() flag the device as open prior to calling the device's open() method, and reflagging it as closed if the open() method fails.
