024cd2cbd1ca2d29e6df538855d52c4e5990cab7 Author: Santucci Pierpaolo Date: Mon Nov 16 11:30:37 2020 +0100 selftest/bpf: Fix IPV6FR handling in flow dissector From second fragment on, IPV6FR program must stop the dissection of IPV6 fragmented packet. This is the same approach used for IPV4 fragmentation. This fixes the flow keys calculation for the upper-layer protocols. Note that according to RFC8200, the first fragment packet must include the upper-layer header.
