Re: [PATCH] network hotplug via class_device/kobject

   Paranoid about some driver doing something like:
   	rtnl_lock(); register_netdevice(); unregister_netdevice();
rtnl_unlock() BOOM

These sorts of turds exist at least in two places:

1) drivers/net/wan/comx.c
2) drivers/net/wan/hdlc_fr.c

But it is pretty clear that these two drivers have been
tried by nobody in recent years.  They both call into
{un,}register_netdevice without the RTNL semaphore held.

Not sure about 1), but 2) calls (un)register_netdevice() with rtnl_lock,
from ioctl.
