From: Menglong Dong <imagedong@xxxxxxxxxxx> [ 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.
