[PATCH v2 net-next 0/5] Introduce matching on double vlan/QinQ headers for TC flower
Currently TC flower supports only one vlan tag, it doesn't match on both outer and inner vlan headers for QinQ. To do this, we add support to get both outer and inner vlan headers for flow dissector, and then TC flower do matching on those information. We also plan to extend TC command to support this feature. We add new cvlan_id/cvlan_prio/cvlan_ethtype keywords for inner vlan header. The existing vlan_id/vlan_prio/vlan_ethtype are for outer vlan header, and vlan_ethtype must be 802.1q or 802.1ad. The examples for command and output are as the following. # tc filter add dev ens1f1 parent : protocol 802.1ad pref 33 \ 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 ens1f1_0 # tc filter show dev ens1f1 ingress filter protocol 802.1ad pref 33 flower chain 0 filter protocol 802.1ad pref 33 flower chain 0 handle 0x1 vlan_id 1000 vlan_ethtype 802.1Q cvlan_id 100 cvlan_ethtype ip eth_type ipv4 in_hw ... v2: fix sparse warning.
