Calling a NIC driver open function from a context holding a spinlock
is very much the real problem, so many operations have to sleep and
in face that ->ndo_open() method is defined as being allowed to sleep
and that's why the core networking never invokes it with spinlocks

I mean "without" of course. :-)
