s390: scatter-gather for inbound traffic in qeth driver
For large incoming packets > PAGE_SIZE/2 qeth creates a fragmented skb by adding pointers to qdio pages to the fragment list of the skb. This avoids allocating big chunks of consecutive memory. Also copying data from the qdio buffer to the skb is economized.
