This patchset introduces a new ethdev API:
- rte_eth_rx_descriptor_status()
- rte_eth_tx_descriptor_status()

The Rx API is aims to replace rte_eth_rx_descriptor_done() which
does almost the same, but does not differentiate the case of a
descriptor used by the driver (not returned to the hw).

The usage of these functions can be:
- on Rx, anticipate that the cpu is not fast enough to process
  all incoming packets, and take dispositions to solve the
  problem (add more cpus, drop specific packets, ...)
- on Tx, detect that the link is overloaded, and take dispositions
  to solve the problem (notify flow control, drop specific
  packets)

The patchset updates ixgbe, i40e, e1000, mlx5.
The other drivers that implement the descriptor_done() API are
fm10k, sfc, virtio. They are not updated.
If the new API is accepted, the descriptor_done() can be deprecated,
and examples/l3fwd-power will be updated to.

Applied, thanks

Next steps:
- implement it in other drivers
- deprecate descriptor_done API

Ferruh, please, could you check with drivers maintainers?
Thanks
