I'm not sure what it is, but the fact that a variety of nic drivers
are having this
same problem indicates that something changed in the if_timer and its
caller, someone knowing that subsystem would be better qualified to
say what.

The other drivers should do the same thing that em did, and stop using
the net layer timer :)
