net/mlx5e: Allow matching only enc_key_id/enc_dst_port for decapsulation action
In some case, we don't care the enc_src_ip and enc_dst_ip, and
if we don't match the field enc_src_ip and enc_dst_ip, we can use
fewer flows in hardware when revice the tunnel packets. For example,
the tunnel packets may be sent from different hosts, we must offload
one rule for each host.
$ tc filter add dev vxlan0 protocol ip parent ffff: prio 1 \
flower dst_mac 00:11:22:33:44:00 \
enc_src_ip Host0_IP enc_dst_ip 2.2.2.100 \
enc_dst_port 4789 enc_key_id 100 \
action tunnel_key unset action mirred egress redirect dev eth0_1
$ tc filter add dev vxlan0 protocol ip parent ffff: prio 1 \
flower dst_mac 00:11:22:33:44:00 \
enc_src_ip Host1_IP enc_dst_ip 2.2.2.100 \
enc_dst_port 4789 enc_key_id 100 \
action tunnel_key unset action mirred egress redirect dev eth0_1
If we support flows which only match the enc_key_id and enc_dst_port,
a flow can process the packets sent to VM which (mac 00:11:22:33:44:00).
$ tc filter add dev vxlan0 protocol ip parent ffff: prio 1 \
flower dst_mac 00:11:22:33:44:00 \
enc_dst_port 4789 enc_key_id 100 \
action tunnel_key unset action mirred egress redirect dev eth0_1
