Previously the key was used to check the presence of vlan id and prio fields instead of using the mask. Additionally the vlan id field was considered to be present if only the prio field was set, and vice versa. f.e. setting the following: ovs-ofctl -OOpenFlow13,OpenFlow15 add-flow br0 \ priority=10,cookie=1,table=0,ip,dl_vlan_pcp=2,actions=output:2 Resulted in (instead of wildcarding vlan_id, filter matches 0): filter protocol 802.1Q pref 1 flower chain 0 filter protocol 802.1Q pref 1 flower chain 0 handle 0x1 vlan_id 0 vlan_prio 2 vlan_ethtype ip eth_type ipv4 ip_flags nofrag in_hw action order 1: mirred (Egress Redirect to device eth1) stolen index 2 ref 1 bind 1 installed 5 sec used 5 sec Action statistics: Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 cookie 47040ae7a94fff6afd7ed8aa04b11ba4 Signed-off-by: Pieter Jansen van Vuuren <pieter.jansenvanvuuren@netronome.com> Reviewed-by: Simon Horman <horms+renesas@verge.net.au> --- lib/netdev-tc-offloads.c | 2 ++ lib/tc.c | 6 +++++- 2 files changed, 7 insertions(+), 1 deletion(-)
