X-Git-Tag: v4.9.8~6775^2~32 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d2d273ffabd315eecefce21a4391d44b6e156b73;p=platform%2Fkernel%2Flinux-rpi3.git ipv6: Fix exthdrs offload registration. Without this fix, ipv6_exthdrs_offload_init doesn't register IPPROTO_DSTOPTS offload, but returns 0 (as the IPPROTO_ROUTING registration actually succeeds). This then causes the ipv6_gso_segment to drop IPv6 packets with IPPROTO_DSTOPTS header. The issue detected and the fix verified by running MS HCK Offload LSO test on top of QEMU Windows guests, as this test sends IPv6 packets with IPPROTO_DSTOPTS.
