Boris Sukholitko 9c5eee0afc net/sched: act_vlan: Fix modify to allow 0 ... Currently vlan modification action checks existence of vlan priority by comparing it to 0. Therefore it is impossible to modify existing vlan tag to have priority 0. For example, the following tc command will change the vlan id but will not affect vlan priority: tc filter add dev eth1 ingress matchall action vlan modify id 300 \ priority 0 pipe mirred egress redirect dev eth2 The incoming packet on eth1: ethertype 802.1Q (0x8100), vlan 200, p 4, ethertype IPv4 will be changed to: ethertype 802.1Q (0x8100), vlan 300, p 4, ethertype IPv4 although the user has intended to have p == 0. The fix is to add tcfv_push_prio_exists flag to struct tcf_vlan_params and rely on it when deciding to set the priority.
