Link status event Pre-conditions
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Firmware 1.8.0.0 and later versions support reporting link changes to the PF.
Therefore, to use the LSC for the PF driver, ensure that the firmware version
also supports reporting link changes.
If the VF driver needs to support LSC, special patch must be added:
`<https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/drivers/net/ethernet/hisilicon/hns3?h=next-20210428&id=18b6e31f8bf4ac7af7b057228f38a5a530378e4e>`_.
Note: The patch has been uploaded to 5.13 of the Linux kernel mainline.
