This change makes it possible to identify SKBs that have been redirected by TC-BPF (cls_act). This is needed for a number of cases. (1) For collaborating with driver ifb net_devices.

Not sure if anyone actually cares about ifb devices, but my worry is that the generic XDP vs tc interaction has been as-is for quite some time so this change in behavior could break in the wild.
