4.11-stable review patch. If anyone has any objections, please let me know.

From: Girish Moodalbail <girish.moodalb...@oracle.com>
[ Upstream commit 5e0740c445e6ae4026f5e52456ff8d0be9725183 ]
Creating a geneve link with 'udpcsum' set results in a creation of link
for which UDP checksum will NOT be computed on outbound packets, as can
be seen below.
11: gen0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN
link/ether c2:85:27:b6:b4:15 brd ff:ff:ff:ff:ff:ff promiscuity 0
geneve id 200 remote 192.168.13.1 dstport 6081 noudpcsum
Similarly, creating a link with 'noudpcsum' set results in a creation
of link for which UDP checksum will be computed on outbound packets.
Fixes: 9b4437a5b870 ("geneve: Unify LWT and netdev handling.")
