When do we get to merge it?
It is backward compatible to 2.4 netif_rx() which means it can go in now. The problem is netdrivers that want to use the interface have to be morphed. As a general disclaimer, i really dont mean to put down Ingo's efforts i just think the irq mitigation idea as is now is wrong for both 2.4 and 2.5
