[dpdk-dev,v2,1/7] ethdev: add support for ieee1588 timestamping
Commit Message
Add 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()

No, you cannot add new symbols in DPDK_2.0 node.
Please use DPDK_2.1 node.
