From 04d8825c30b718781197c8f07b1915a11bfb8685 Mon Sep 17 00:00:00 2001 From: Paolo Abeni Date: Wed, 22 Sep 2021 19:26:40 +0200 Subject: [PATCH] tcp: expose the tcp_mark_push() and tcp_skb_entail() helpers the tcp_skb_entail() helper is actually skb_entail(), renamed to provide proper scope. The two helper will be used by the next patch.
