Hi Dave,

I have a qeth patch which uses napi_gro_flush (not posted yet).
There is following idea:

The inbound processing of the qeth driver is already in bottomhalf
(qdio input tasklet) so we can switch from netif_rx to
netif_receive_skb. This allows us to exploit gro code for the
layer 3 driver. I would introduce a dummy napi_struct and call
napi_gro_flush when the inbound tasklet ends.

Should I post the patch for review?

Thanks,
  Frank
