Title:
  Commit "net/mlx5e: Don't offload internal port if filter device is out
  device" breaks OpenStack/OVN distributed gateway use case

Status in linux package in Ubuntu:
  New

Bug description:
  Consider a topology with two chassis, A and B:
  * A acts as a distributed gateway connected to provider network on tagged 
VLAN and has GENEVE tunnel configured towards chassis B.
  * B hosts the target instance.
  * From a third machine connected to the provider network we can observe:
    * Only first ICMP ECHO reply from target instance is forwarded.
    * Attempt to establish TCP connection fails.

  If we revert commit [0] the symptoms disappear.
