I believe that is incorrect, unfortunately. See below.

I suspect they are equipped with the same ROC controller that the
ARC-1880 series uses. I don't recall at the moment exactly what
controller it is, but it definitely is not the Intel IOP348 that's
in some of the other ARC-1200 series (as well as ARC-1680), and it is
AFAIK *not* presently supported by the arc(4) driver. Which is
unfortunate, since they are excellent controllers with much bang for
the buck.
I actually made a stab at implementing support for the ARC-1880i using
the FreeBSD driver as inspiration, but alas ran out of time on the
project I was intent on using them in, so we had to revert to ARC-1680i
(which are now unfortunately no longer sold).
