NAPI doesn't make sense for virtual devices, my Sun LDOM nework
driver won't use NAPI either.

It's also too cumbersome to use NAPI with the way virtualized
network drivers work (multiple ports, each with an interrupt
source, not just one) until the NAPI split patches are ported
and applied upstream and that won't be for a while.
