Merge branch 'lift-udp_segment-restriction-for-egress-via-device-w-o-csum-offload'
Jakub Sitnicki says:
====================
Lift UDP_SEGMENT restriction for egress via device w/o csum offload
This is a follow-up to an earlier question [1] if we can make UDP GSO work
with any egress device, even those with no checksum offload capability.
That's the default setup for TUN/TAP.
Because there is a change in behavior - sendmsg() does no longer return
EIO error - I'm submitting through net-next tree, rather than net,
as per Willem's advice.
