net: add a couple of helpers for iph tot_len
[ Upstream commit 058a8f7f73aae1cc22b53fcefec031b9e391b54d ]
This patch adds three APIs to replace the iph->tot_len setting
and getting in all places where IPv4 BIG TCP packets may reach,
they will be used in the following patches.
Note that iph_totlen() will be used when iph is not in linear
data of the skb.
