Thanks Michael, that's a good suggestion and would work.
In thinking about this some more over the weekend I've decided
that my plan to rip out RX support from netpoll is a bit too
ambitious.
Therefore, for the time being, I'm going to add a special driver
function for netpoll that will allow it to ask the driver to invoke
->poll() over all the NAPI structs assosciated with the netdev.
