With the recent flow based tunneling changes, VXLAN support was broken. These
patches address this by enabling VXLAN to work as it did before flow based
tunneling was pushed upstream.

Kyle Mestery (6):
  Modify netdev_vport_get_dpif_port() to return a name for VXLAN ports
    which     includes the destination UDP port number as a part of the
  Modify dpif_linux_port_add() to set the destination port for VXLAN
  Add utility functions to the simap structure. These are used by future
    patches     in this seris. The functions added are.
  Move dpif_backer->tnl_backers from a "struct sset" to a "struct
    simap".     Store odp_port in the new map.  This will make it easier
    to access the     odp_port for future patches.
  In tnl_set_config(), when determining if a tunnel port already exists,
    make     sure to also check the destination port. For VXLAN, this
    can be different     and allows multiple VXLAN ports in the datapath
    to be created.
  Garbage collect tnl_backers during type_run(). Add new tnl_backers if
    a VXLAN     ports UDP port changes.
