3.16.37-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Hannes Frederic Sowa <hannes@stressinduktion.org>
commit dcb94b88c09ce82a80e188d49bcffdc83ba215a6 upstream.
IPv6 ping socket error handler doesn't correctly convert the new 32 bit mtu to host endianness before using.
