Sigh, there are even more issues.  Now dev_kfree_skb()
is illegal in ->hard_start_xmit() because interrupts are
disabled, and there are many such cases in the simpler
net drivers.

I think we might need to revert the change over to IRQ
disabling dev->xmit_lock and rethink this.  This is just too
much fallout.
