[ovs-dev] [PATCH] Update default VXLAN UDP port to official IANA port

[Kyle Mestery]

VXLAN was recently assigned UDP port 4789 by IANA. This updates the OVS VXLAN
implementation to reflect the new UDP port number. It also updates the unit
test for VXLAN to pass with the change in UDP port number.
