ZFS TRIM support for Pass Through SSD on Areca card.

When I check the TRIM support for the drives I get "unsupported":
zpool status -t zroot
pool: zroot
state: ONLINE
config:

NAME STATE READ WRITE CKSUM
zroot ONLINE 0 0 0
mirror-0 ONLINE 0 0 0
da0p3 ONLINE 0 0 0 (trim unsupported)
da1p3 ONLINE 0 0 0 (trim unsupported)

errors: No known data errors

But of it is supported :
smartctl -x --device=areca,1/1 /dev/arcmsr0 | grep -i trim
TRIM Command: Available, deterministic, zeroed

Is it possible for ZFS to somehow "see" that? I guess this is the problem:
smartctl -x /dev/da0 | grep -i trim (empty line)

Regards.
 
For anybody having a similar problem, I just updated to the latest Areca firmware and now it translates the TRIM command correctly to the SSDs :

pool: zroot
state: ONLINE
config:

NAME STATE READ WRITE CKSUM
zroot ONLINE 0 0 0
mirror-0 ONLINE 0 0 0
da0p3 ONLINE 0 0 0 (untrimmed)
da1p3 ONLINE 0 0 0 (untrimmed)

errors: No known data errors
