Bug description:
  [Impact]
  With Hardware Offload enabled, traffic from network with SNAT enabled can't reach service behind a Load Balancer's VIP.

  Fix was proposed and merged upstream [0] and additional discussion can
  be found on mailing list [1].

  [0] https://github.com/ovn-org/ovn/commit/342eb7fec33392642bb7b79526851bb1f4eda880
  [1] https://mail.openvswitch.org/pipermail/ovs-dev/2025-May/423389.html

  [Test Case]
  The change includes both unit and system test cases that will be executed as part of package build and autopkgtest.

  In addition full end to end validation will be performed as documented
  in the test case for point release updates submitted simultaneously
  (bug 2119301, bug 2119289 and bug 2119283).

  [Regression Potential]
  The patch, which in reality is a revert of a previous commit, has been merged and backported to upstream stable branches [2] since June 25th.

  The change has received scrutiny from maintainers of the project as
  well as stake holders among hardware vendors.
