ipv6: Partial checksum only UDP packets
ip6_append_data is used by other protocols and some of them can't be partially checksummed. Only partially checksum UDP protocol. Fixes: 32dce968dd987a (ipv6: Allow for partial checksums on non-ufo packets) Reported-by: Sabrina Dubroca <sd@queasysnail.net> Tested-by: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: Vladislav Yasevich <vyasevic@redhat.com> Signed-off-by: David S.
