[PATCH net-next 02/10] net: sched: add skbedit of ptype action to hardware IR

[John Hurley <john.hurley@netronome.com>]

TC rules can impliment skbedit actions. Currently actions that modify the
skb mark are passed to offloading drivers via the hardware intermediate
representation in the flow_offload API.

Extend this to include skbedit actions that modify the packet type of the
skb. Such actions may be used to set the ptype to HOST when redirecting a
packet to ingress.
