+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:

the patch has been merged.
+Note: The patch has been uploaded to 5.13 of the Linux kernel mainline.

I am not sure about documenting a not released kernel patch for the
support,
what about waiting kernel release for support?
Hi, Ferruh, all,
5.13 kernel has released:
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/drivers/net/ethernet/hisilicon/hns3?h=next-20210428&id=18b6e31f8bf4ac7af7b057228f38a5a530378e4e
