[PATCH net] gro: Disable frag0 optimization on IPv6 ext headers

2017-01-10 Thread Eric Dumazet
From: Herbert Xu The GRO fast path caches the frag0 address. This address becomes invalid if frag0 is modified by pskb_may_pull or its variants. So whenever that happens we must disable the frag0 optimization. This is usually done through the combination of gro_header_hard and gro_header_slow,
