#1572595 — [PATCH 4.9 18/51] vxlan: fix byte order of vxlan-gpe port number

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

------------------

From: Lance Richardson <lrichard@redhat.com>


[ Upstream commit d5ff72d9af73bc3cbaa3edb541333a851f8c7295 ]

vxlan->cfg.dst_port is in network byte order, so an htons()
is needed here. Also reduced comment length to stay closer
to 80 column width (still slightly over, however).
