ip link: Fix vlan proto, closes 8261 and 11638
The proto has to be passed in network byte-order.
While at it allow for
ip link add link eth0 name eth0.2.24 type vlan proto 802.1ad id 24
ip link del link eth0 name eth0.2.24 type vlan proto 802.1ad id 24
The del was lacking a dev_str and thus errored out. Fix by using
name/dev counterpart as fallback.
The proto identifier 802.1Q was not recognized, just it's lowercase
variant, fix that too.
