The encapsulation is not supported for mlx5 VFs. When we try to
offload that action, the -EINVAL is returned, but not -EOPNOTSUPP.
This patch changes the returned value and ignore to confuse user.
For example: (p2p1_0 is VF net device)
tc filter add dev p2p1_0 protocol ip parent ffff: prio 1 flower skip_sw \
src_mac e4:11:22:33:44:01 \
action tunnel_key set \
src_ip 1.1.1.100 \
dst_ip 1.1.1.200 \
dst_port 4789 id 100 \
action mirred egress redirect dev vxlan0
"RTNETLINK answers: Invalid argument"
