Title:
  Fix host to pod traffic with ovn cluster using ovs internal port and
  tc offload

Status in linux-bluefield package in Ubuntu:
  Invalid
Status in linux-bluefield source package in Focal:
  Fix Committed

Bug description:
  * Explain the bug(s)

  When using ovs internal port with tc the redirect rules to internal port is 
back
  to ingress instead of egress.
  When we reinsert the skb we start from chain 0 but it could be ct state 
already
  set so matching rules on the internal port queue would miss.

  * brief explanation of fixes

  When reinserting skb back to ingress queue to restart tc
  classification then also reset ct.

  * How to test

  The setup was created by using ovn and testing iperf traffic from host 
container to VF pod.
  The result was ip set on the ovs bridge netdev (internal port)
  The rules were from rep to eventually the internal port and internal port to 
rep.
  The rules were with ct actions and chains tc-policy was set to skip-hw.
  Without the commit the traffic doesn’t work when hw-offload was true (offload 
to tc sw only) but
  does work with hw-offload false (ovs dp).

  * What it could break.

  Traffic not working in some cases using internal ports and CT.
