3.5-stable review patch. If anyone has any objections, please let me know.
------------------
From: Antonio Quartulli <or...@autistici.org>
[ Upstream commit 5316cf9a5197eb80b2800e1acadde287924ca975 ]
skb_reset_mac_len() relies on the value of the skb->network_header pointer,
therefore we must wait for such pointer to be recalculated before computing
the new mac_len value.
