net: Postpone skb_clear_delivery_time() until knowing the skb is delivered locally
The previous patches handled the delivery_time in the ingress path before the routing decision is made. This patch can postpone clearing delivery_time in a skb until knowing it is delivered locally and also set the (rcv) timestamp if needed. This patch moves the skb_clear_delivery_time() from dev.c to ip_local_deliver_finish() and ip6_input_finish(). Signed-off-by: Martin KaFai Lau <kafai@fb.com> Signed-off-by: David S.
