From 259187704c6051544505be37846d6cc6662de085 Mon Sep 17 00:00:00 2001 From: Menglong Dong Date: Thu, 27 Jan 2022 17:13:01 +0800 Subject: [PATCH] net: socket: rename SKB_DROP_REASON_SOCKET_FILTER Rename SKB_DROP_REASON_SOCKET_FILTER, which is used as the reason of skb drop out of socket filter before it's part of a released kernel. It will be used for more protocols than just TCP in future series.
