Currently, VF driver periodically obtains link status from PF kernel driver, and reports lsc event when detects link status change. Because the period is 1 second, it's probably too late to report especially in such as bonding scenario. To solve this problem we use the following scheme: 1. PF kernel driver support immediate push link status to all VFs when it detects the link status changes. 2. VF driver will detect PF kernel driver whether support push link status in device init stage by sending request link info mailbox message to PF, PF then tell VF the push capability by extend HNS3_MBX_LINK_STAT_CHANGE mailbox message. 3. VF driver marks RTE_PCI_DRV_INTR_LSC in rte_pci_driver by default, when it detects PF doesn't support push link status then it will clear RTE_ETH_DEV_INTR_LSC flag. So if PF kernel driver supports push link status to VF, then VF driver will have RTE_ETH_DEV_INTR_LSC capability.
