Well, it holds bdp->isolate_lock for an incredibly long time, so that
might trigger this. At least interrupts aren't disabled.
Another bug: e100_close doesn't get the lock.

Cosmetic or real, that's indeed another bug...

This came up earlier and we're working on getting rid of isolate_lock
altogether. It's a bunch of complication for no real benefit, really.

We'll I guess no link would give you a speed of zero Mbps. ;)
I'm inclined to strike this message line because it's 1) misleading, 2)
redundant.
