[SRU][N:gcp][PATCH 0/1] Backport "netkit: Add option for scrubbing skb meta data" to 6.8

[Tim Whisonant]

BugLink: https://bugs.launchpad.net/bugs/2091184

SRU Justification:

[Impact]

* GCP states that they would like to leverage NetKit for better
  networking performance, and that recent fixes that have landed in
  mainline are necessary to avoid bugs when using Cilium.

[Fix]

* 83134ef46093 netkit: Add option for scrubbing skb meta data
  This was a clean cherry-pick onto 6.8.

[Test Plan]

* Boot-tested the changes in GCP environment on amd64 hardware.

[Where problems could occur]

* When running Cilium with NetKit in per-endpoint-routes mode, network
  policy misclassifies traffic. This mode is used in the case of
  GKE/EKS/AKS.

[Other Info]

* Changes are limited to the NetKit driver. Risk is considered low as
  the changes are limited and apply cleanly from upstream.
