To support matching on both outer and inner vlan headers,
we add new cvlan_id/cvlan_prio/cvlan_ethtype for inner vlan header.
Example:
# tc filter add dev eth0 protocol 802.1ad parent ffff: \
flower vlan_id 1000 vlan_ethtype 802.1q \
cvlan_id 100 cvlan_ethtype ipv4 \
action vlan pop \
action vlan pop \
action mirred egress redirect dev eth1
# tc filter show dev eth0 ingress
filter protocol 802.1ad pref 1 flower chain 0
filter protocol 802.1ad pref 1 flower chain 0 handle 0x1
vlan_id 1000
vlan_ethtype 802.1Q
cvlan_id 100
cvlan_ethtype ip
eth_type ipv4
