Easy, the driver is already allocating them right now so we don't have to change a thing :)
All we have to do is change the refill mechanism to always allocate a replacement skb in the rx path, and if that fails, allocate a fragmented skb instead and copy the received data into it so that the contiguous skb can be reused.
