Allow default ip_proto to offload, so icmp, tcp, and udp
will match the flow as show below, otherwise we must type the
ip_proto for icmp, tcp and udp respectively.
$ tc filter add dev netdev01_rep parent ffff: protocol ip prio 1 \
flower skip_sw dst_ip 3.3.3.3 \
action pedit ex munge ip dst set 192.168.1.100 pipe \
action csum ip pipe \
action mirred egress redirect dev netdev02_rep
