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
