Subject: [PATCH] selftest/bpf: fix IPV6FR handling in flow dissector
Date: Tue, 10 Nov 2020 18:12:13 +0100	[thread overview]
Message-ID: <X6rJ7c1C95uNZ/xV@santucci.pierpaolo> (raw)

From second fragment on, IPV6FR program must stop the dissection of IPV6
fragmented packet. This is the same approach used for IPV4 fragmentation.
