State-Changed-Why:
(Side note: the real bug was in uncommited code and has been fixed a logn
time ago, this PR only has been kept open as a reminder to analyze the
locking problem mentioned in passing by Andrew)
Looked at it again and it is no real problem right now: nwords won't
change while we are sleeping: we own KERNEL_LOCK, and we don't attach
any phy's to already attached interfaces - so the list just won't change.
Matt Thomas agrees.
