--- Comment #1 from Mark Johnston <markj@FreeBSD.org> ---
ccp(4) appears to have a constraint that the AAD length with AES-GCM must b=
e a
multiple of the cipher block size.  ZFS doesn't handle the errors that resu=
lt
when it submits a request satisfying this constraint.  See bug 252981 for a
related example of the same problem.  For 13.0 this will be worked around by
simply disabling the use of hardware offloads by ZFS.
