Hi Yuri,

Sorry for the late reply!

Tried on
and found it's OK for nda. If not add "hw.nvme.use_nvd="0"" in
"/boot/loader.conf", it still can work by nda.

Also tried on FreeBSD 13.2GA, it's OK for nda too. If not use nda, it still
cannot  recognize the newly added NVMe hard disk.

So, does it mean we can just use nda for FreeBSD in the future? 

If we use nda, we need to add "hw.nvme.use_nvd="0"" in FreeBSD 13.x. When we
can support this function by default in FreeBSD 13.x? Or, just support it from
FreeBSD 14.x?
