| |
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.
