Performance drop when enabling Rx timestamp offloading is a known issue, actually, the patch reduces the downgrade.
Refined the commit log to :
This patch enables Rx timestamp offload on the vector data path.
It significantly reduces the performance drop when RTE_ETH_RX_OFFLOAD_TIMESTAMP is enabled.
