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.

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.

By then, we'll add it in hns3.ini.
