This patch support LSC(Link Status Change) event report.
There is a user config for lsc, 'dev->data->dev_conf.intr_conf.lsc',
which seems not taken into account.
Frist of all, thank you for your review. Currently, the old firmware
doest not support interrupt reporting. Therefore, the PF does not suport
interrupt reporting through the mailbox. Therefore, the PF obtains
interrupts in polling mode and then reports interrupts.
Also 'RTE_PCI_DRV_INTR_LSC' should be set in 'rte_pci_driver.drv_flags'
to report this feature to higher levels.
In the future, the new firmware + PF will support interrupt reporting.
In that case, the LSC capability of dev_flag will be set.
In the future, we will enable the VF to support LSC. That is, we are
developing the PF to report LSC interrupts through the mailbox.
And when the feature is fully implemented, can you please add "Link
status event" feature to 'hns3.ini'?
By then, we'll add it in hns3.ini.
