NAPI question about old drivers

[Jason Lunz <j@xxxxxxxxxxxxxx>]

I'm reading the NAPI patch and I don't understand how old drivers can
continue to work.

in net_rx_action(), NAPI does this:

        if (dev->quota <= 0 || dev->poll(dev, &budget)) {

what happens to legacy drivers that don't set dev->poll? I see
netif_rx() has been modified, but drivers that call that and don't have
a dev->poll will be in trouble when net_rx_action() runs.

am i missing something?
