3.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jesse Gross <jesse@xxxxxxxxxx>
[ Upstream commit 7ed767f73192d6daf673c6d885cd02d5f280ac1f ]
Sockets aren't currently removed from the the global list when
they are destroyed. In addition, offload handlers need to be cleaned
up as well.
Fixes: 0b5e8b8e ("net: Add Geneve tunneling protocol driver")
