net: Inline skb_pull() in eth_type_trans().
In commit 6be8ac2f ("[NET]: uninline skb_pull, de-bloats a lot") we uninlined skb_pull. But in some critical paths it makes sense to inline this thing and it helps performance significantly. Create an skb_pull_inline() so that we can do this in a way that serves also as annotation. Based upon a patch by Eric Dumazet. Signed-off-by: David S. Miller <davem@davemloft.net>
