christos applied the dump changes for extattrs from freebsd to our code last year:

commit 52fea75266aee4480e62dd763d4d3d74b002ea5c
Author: christos <christos%NetBSD.org@localhost>
Date:   Sat Jun 19 13:56:34 2021 +0000

    Add external attribute dumping and restoring support from FreeBSD.
    Does not fully work yet, attributes are being saved and restored correctly,
    but don't appear in the restored files somehow.


there is a bug in that code that effectively prevents restoring NFSv4 ACLs.
I have a fix for this bug that I need to apply to freebsd and then I'll apply it
to our code as well.
