From 6c2728b7c14164928cb7cb9c847dead101b2d503 Mon Sep 17 00:00:00 2001 From: Menglong Dong Date: Fri, 4 Mar 2022 14:00:46 +0800 Subject: 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.
