The implementation is incomplete, To support LSC in i40evf, please 1. add RTE_PCI_DRV_INTR_LSC in drv_flags 2. make sure dev_conf.intr_conf.lsc can be configure with 1 3.update i40e_vf.ini.

When PF event VIRTCHNL_EVENT_LINK_CHANGE received, i40evf need update the link status and issue RTE_ETH_EVENT_INTR_LSC via _rte_eth_dev_callback_process().
