[dpdk-dev] [PATCH v4 0/7] ethdev: add support for ieee1588 timestamping

[John McNamara]

This patchset adds ethdev API to enable and read IEEE1588/802.1AS PTP
timestamps from devices that support it. The following functions are added:

    rte_eth_timesync_enable()
    rte_eth_timesync_disable()
    rte_eth_timesync_read_rx_timestamp()
    rte_eth_timesync_read_tx_timestamp()

The "ieee1588" forwarding mode in testpmd is also refactored to demonstrate
the new API and to clean up the code.

Adds support for igb, ixgbe and i40e.

V4:
* Added timesync field to end of mbuf to pass IEEE1588 registers and flags.
  Removed previous ABI deprecation notice.

V3:
* Fixed issued with version.map.

V2:
* Added i40e support.

* Renamed ethdev functions from rte_eth_ieee15888_*() to rte_eth_timesync_*()
  since 802.1AS can be supported through the same interfaces.

V1:
* Initial version for igb and ixgbe.
