I guess that the problem is the use of netif_receive_skb instead of
netif_rx? I made the change because to my understanding netif_rx should
not be used in the NAPI poll function. Perhaps that is not correct?
The uses of netif_napi_del happen in error handling code of the probe
function and in the remove function, and it doesn't seem like that code is
being executed here?

> drivers/net/ethernet/via/via-velocity.c: update napi implementation
>
> Drivers supporting NAPI should use a NAPI-specific function for receiving
> packets. Hence netif_rx is changed to netif_receive_skb.
>
> Furthermore netif_napi_del should be used in the probe and remove function
> to clean up the NAPI resource information.
>
> Thanks to Francois Romieu, David Shwatrz and Rami Rosen for their help on
