ZFS Trim on mps?

Should I be getting trim with ZFS on an mps device?

Disks are SATA ssd (830s), only "unsupported" is being reported.
Do I need to set the cam "da" delete method to something (unmap?), or is
ZFS trim only supported on ahci sata controllers?

vfs.zfs.trim_disable: 0
vfs.zfs.trim_txg_limit: 64
kstat.zfs.misc.zio_trim.bytes: 0
kstat.zfs.misc.zio_trim.success: 0
kstat.zfs.misc.zio_trim.unsupported: 281
