My next step is to provide a common helper to NAPI drivers to replace 
netdev_alloc_skb_ip_align(struct net_device *dev, unsigned int len)

by :

struct sk_buff *napi_alloc_rxskb(struct napi_struct *napi, unsigned int len)

That will manage a cache of one page, splitted in fragments as needed.
(roughly the code we added in tg3 as POC)

Because converting drivers to build_skb() is a too slow process.

Sounds good.
