This is required since the receive handling that is used by the redirect to ingress action checks whether the packet doesn't belong to this host and drops the packet in such case. In order to be able to offload action redirect ingress, tc offload code needs to accept the skbedit ptype action as well. There's no special handling in HW for such action since it will be followed by a redirect action and therefore, this code only allows us to accept such action in the actions list but not performing anything specific in HW for it.
