Subject: [PATCH 4.4 13/20] [PATCH] netvsc: Set maximum GSO size in the right place

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ben Hutchings <ben@...adent.org.uk>

Commit a50af86dd49e "netvsc: reduce maximum GSO size" was wrongly
backported to 4.4-stable.  The maximum size needs to be set before the
net device is registered, in netvsc_probe().
