[dpdk-dev] [PATCH 0/4] ethdev: add support for ieee1588 timestamping

[John McNamara <john.mcnamara@intel.com>]

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

    rte_eth_ieee1588_enable()
    rte_eth_ieee1588_disable()
    rte_eth_ieee1588_read_rx_timestamp()
    rte_eth_ieee1588_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 and ixgbe. Support for i40e will follow in V2.

I would be interested in getting feedback from maintainers of non-Intel pmds
on whether this interface is sufficient to initialise, read from, and stop,
IEEE1588 functionality on other devices.
