Currently, PF driver will report lsc when it detects the link status change, it's not a generic implementation. We refactor PF lsc event report by following scheme: 1. PF driver marks RTE_PCI_DRV_INTR_LSC in rte_pci_driver by default. 2. In the init stage, PF driver will detect whether firmware supports lsc interrupt or not, driver will clear RTE_ETH_DEV_INTR_LSC flag if firmware doesn't support lsc interrupt. 3. PF driver will report lsc event only when dev_conf.intr_conf.lsc is set. Note: If the firmware supports lsc interrupt, we also keep periodic polling to deal with the interrupt loss.
