net/act_pedit: Introduce 'add' operation
This command could be useful to inc/dec fields. For example, to forward any TCP packet and decrease its TTL: $ tc filter add dev enp0s9 protocol ip parent ffff: \ flower ip_proto tcp \ action pedit munge ip ttl add 0xff pipe \ action mirred egress redirect dev veth0 In the example above, adding 0xff to this u8 field is actually decreasing it by one, since the operation is masked.
