It is quite straightforward, use new perfect function to repalce old ones for clearing hardware before doing PF reset. * add required steps in TX queue enable, disable. Hardware specification changed recently which requries additional steps. Without the steps, DPDK might be not able to transmit packets after standard Linux i40e driver loaded.
