net: dev: use kfree_skb_reason() for __netif_receive_skb_core()
Add reason for skb drops to __netif_receive_skb_core() when packet_type not found to handle the skb. For this purpose, the drop reason SKB_DROP_REASON_PTYPE_ABSENT is introduced. Take ether packets for example, this case mainly happens when L3 protocol is not supported. Signed-off-by: Menglong Dong <imagedong@tencent.com> Signed-off-by: David S. Miller <davem@davemloft.net>
