Merge branch 'xmit_more-softnet_data'

Florian Westphal says:

====================
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.
