Shouldn't it be register_pernet_gen_subsys ?
If you use register_pernet_gen_device, your subsystem will be deleted
before the network devices and potentially you can receive a packet even
if your subsystem is already freed.
Eric did a fix for tcp and icmp a few weeks ago. I thing its explanation

it is the commit 6eb0777228f31932fc941eafe8b08848466630a1 for net-2.6
Thanks.
