Merge branch 'don-t-take-hw-uso-path-when-packets-can-t-be-checksummed-by-device'
Jakub Sitnicki says:
====================
Don't take HW USO path when packets can't be checksummed by device
This series addresses a recent regression report from syzbot [1].
After enabling UDP_SEGMENT for egress devices which don't support checksum
offload [2], we need to tighten down the checks which let packets take the
HW USO path.
The fix consists of two parts:
1. don't let devices offer USO without checksum offload, and
2. force software USO fallback in presence of IPv6 extension headers.
