I'll close this revision now that the underlying problem has apparently been fixed.

@ziaee I tested the LSI SAS 3908 (MegaRAID 9560 8i), with 14.3-RELEASE. The mrsas driver is automatically loaded, it works with either JBOD mode or RAID0. However, after devctl detach -f and devctl set driver -f device mpr, devctl responded with "device not configured". Even with hint.mpr.0.at="pcix:y:z" in device.hints, the mrsas driver will be loaded instead of the mpr one. In my test, mpr driver does not support SAS 3908, at least with the current firmware.

Awesome, thank you so much. When you test it tomorrow, could you also test blacklisting it and using mrsas as well? We've been having a big problem trying to identify what is supported lately, and we do have an open review for it:

IIRC, I only have LSI 3808 (MegaRAID 9500 8i), and I could test it tomorrow. The original mailing list about LSI 3808 I found is Re: SAS3808 PCI-E 4.0, FreeBSD / ZFS support ?.

Have you tested this? There is also a newer driver called mrsas.

Thank you so much. Tested, confirmed, and pushed!

Seems reasonable to me, thanks!

Can any SME's confirm so we can get this in?

This is a very nice improvement over not having a flua man page!

Is the fix for PR 121440 to close as not a bug?
I'm not sure what to do otherwise, based on your comment.

Not really part of this specific problem, but jail(8) should auto-recognize list parameters because their SYSCTL_JAIL specification has a type with ",a" appended. Ideally, it would build a list of such parameters it sees like that. For non-kernel parameters like vnet.interface and zfs.dataset, putting them in the array is probably as good as its going to get.

Looks good to me.

The tests looks good. I need some time to read the code carefully ...
