Subject: [PATCH net-next 0/5] net: move skb->xmit_more to percpu softnet data

Eric Dumazet mentioned we could place xmit_more hint in same
spot as device xmit recursion counter, instead of using
an sk_buff flag bit.

This series places xmit_recursion counter and xmit_more hint
in softnet data, filling a hole.

After this, skb->xmit_more is always zero.  Drivers are converted
to use "netdev_xmit_more()" helper instead.

Last patch removes the skb->xmit_more flag.

Florian Westphal (5):
      net: place xmit recursion in softnet data
      net: move skb->xmit_more hint to softnet data
      drivers: mellanox: use netdev_xmit_more() helper
      drivers: net: sfc: use netdev_xmit_more helper
      drivers: net: aurora: use netdev_xmit_more helper
