virtio_net: Clean up set_skb_frag()
Remove manual initialization in set_skb_frag, and instead use __skb_fill_page_desc() to do the same. Patch tested on net-next. Signed-off-by: Krishna Kumar <krkumar2@in.ibm.com> Acked-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
