[dpdk-dev] [PATCH v5 1/7] ethdev: add additional ieee1588 support functions

[Daniel Mrzyglod]

Add additional functions to support the existing IEEE1588
functionality.

* rte_eth_timesync_settime(), function to set the device clock time.
* rte_eth_timesync_gettime, function to get the device clock time.
* rte_eth_timesync_adjust, function to adjust the device clock time.
