Bug description:
  [SRU Justification]

  [Impact]

  Packets encapsulated into a vxlan tunnel with openvswitch don't have
  the same udp source port for the first packet and the following ones
  of the same TCP flow in a DOCKER scenario usecase.

  In fact, when using the kernel datapath, the upcall don't include skb hash info relatived. As VXLAN module uses
  the skb hash to select UDP src port, the source port is different for the first packet. 

  More information can be found here:
  https://mail.openvswitch.org/pipermail/ovs-dev/2019-October/364062.html

  This has been fixed in the next release openvswitch 2.13  by the following upstream commits:
  - 0442bfb11d6ccb ("ofproto-dpif-upcall: Echo HASH attribute back to datapath.")
  - c4d8a4e0399910 ("ofproto-dpif: Fix using uninitialized execute hash.")
  - 924d94a695a6ca ("ofproto-dpif-upcall: Fix using uninitialized upcall hash.")

  The bug exists since the beginning of vxlan support in openvswitch.
   
  == Fix ==

  
  Backport the requested patches to Focal (5.4), Disco (5.0), Bionic (4.15) and
  Xenial (4.4).
