net: vlan: add 802.1ad support
Add support for 802.1ad VLAN devices. This mainly consists of checking for
ETH_P_8021AD in addition to ETH_P_8021Q in a couple of places and check
offloading capabilities based on the used protocol.
Configuration is done using "ip link":
# ip link add link eth0 eth0.1000 \
type vlan proto 802.1ad id 1000
# ip link add link eth0.1000 eth0.1000.1000 \
type vlan proto 802.1q id 1000
