Again, not sure if this is the right policy. Seems to me that on a
bonding device we should simply pick an interface to send netpoll
messages on, without reference to balancing, etc. Thus, if any of the
bonded devices supports polling, it should work.

Hopefully someone more familiar with the goals and philosophy of the
bonding code can comment further.
