Subject: [PATCH 5.15 077/201] net: socket: rename SKB_DROP_REASON_SOCKET_FILTER

From: Menglong Dong <imagedong@...cent.com>

[ Upstream commit 364df53c081d93fcfd6b91085ff2650c7f17b3c7 ]

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.
