Hi all,
Today's linux-next merge of the net tree got a conflict in
net/ipv4/ip_output.c between commit
26cde9f7e2747b6d254b704594eed87ab959afa5 ("udp: Fix bogus UFO packet
generation") from the net-current tree and commit
d8d1f30b95a635dbd610dcc5eb641aca8f4768cf ("net-next: remove useless union
keyword") from the net tree.
Just context changes. I fixed it up (see below) and can carry the fix as
necessary.
