I will add a patch which introduce the two functions:

lowpan_register_netdevice - register_netdevice (without rtnl lock)
lowpan_register_netdev - register_netdev (with rtnl lock)

These two functions will call register_netdevice/register_netdev and 6lowpan
debugfs init.


I will remove the lowpan_netdev_unsetup function and introduce a:

lowpan_unregister_netdevice - unregister_netdevice

which calls unregister_netdevice and lowpan_dev_debugfs_exit. I will
change the uninit to exit.

Then we keep the same naming stuff like netdev and these function should
always called when doing register_netdev/unregister_netdev for all
lowpan interface.

Then we can also move lowpan_netdev_setup before register_netdev. This
will move more functionality which should be the same on all lowpan
interfaces into the net/6lowpan branch.
