Sometime after kernel 3.10.0-514.16.1.X, tc filter commands no longer
match 802.1q packets when the filter protocol is set to 'ip'.
This poses a problem for a consolidated (eg. infra w/ vlan over
management) interface configuration.
The tc filter will operate properly on the vlan interface, but all
traffic will go to the default qdisc (low priority) when it arrives
with a vlan tag at the sub-interface.
This commit sets the filter protocol to '802.1q' in the case of a
subinterface with a vlan tagged interface ontop of it.
Some bashate cleanup has also been done on this file.
