One of the values checked is IPPROTO_HOPOPTS, which is defined as 0. If proto field is not specified for matching, or mask=0, as in the following, a wrong validation takes place. flow create 0 ingress pattern eth / ipv6 has_frag_ext is 0 / end actions drop / end Fix the validation only on proto asked by the user.
