No, I'm afraid not. Libsas has been released for nearly seven years an= d no-one has noticed in all that time, which means it's a really rare thing to do. Everyone who uses SAS controllers usually has either a direct connection or an expander. There's no real reason to buy expensive kit and then plug it into a cheap port switch. That said, it's possible that some of the firmware SAT blob based controllers, lik= e the MPT ones might have PMP support ... but because of the rarity it's likely to be buggy.
