From: Ophir Munk <ophirmu@mellanox.com>

IANA has assigned port 6081 as the fixed well-known destination port for
GENEVE. Nevertheless draft-ietf-nvo3-geneve-09 recommends that
implementations make this configurable.  This commit enables specifying
any positive UDP destination port number for GENEVE.
