Looks OK, although I chose another way to disable RX IRQs :)

Sad thing is because of bad MAL design NAPI will be limited to one
EMAC per MAL (there is no way to disable IRQ generation on channel
basis), it's not an issue for 405, but for 440 I haven't figured
out how to overcome this limitation yet.

Andrew, I'm just curious, you probably did some measurements with
your NAPI driver, care to share them :) ?
