This patch-set inspired by [1] from Bhanuprakash Bodireddy.
Implementation of [1] looks very complex and introduces many pitfalls for
later code modifications like possible packet stucks.
This version targeted to make simple and flexible output packet batching on
higher level without introducing and even simplifying netdev layer.
Patch set consists of 3 patches. All the functionality introduced in the
first patch. Two others are just cleanups of netdevs to not do unnecessary
things.
Basic testing of 'PVP with OVS bonding on phy ports' scenario shows
significant performance improvement.
More accurate and intensive testing required.
[1] [PATCH 0/6] netdev-dpdk: Use intermediate queue during packet transmission.

Version 2:
* Rebased on current master.
* Added time based batching RFC patch.
* Fixed mixing packets with different sources in same batch.
Ilya Maximets (4):
dpif-netdev: Output packet batching.
netdev: Remove unused may_steal.
netdev: Remove useless cutlen.
dpif-netdev: Time based output batching.
