4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Richard Alpe <richard.alpe@ericsson.com>
commit 9bd160bfa27fa41927dbbce7ee0ea779700e09ef upstream.
Expand headroom further in order to be able to fit the larger IPv6 header. Prior to this patch this caused a skb under panic for certain tipc packets when using IPv6 UDP bearer(s).
