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):
