Subject: [PATCH 1/1] scsi: aacraid: resurrect correct arc ctrl checks for Series-6
This partially reverts ms commit
395e5df79a95 ("scsi: aacraid: Remove reference to Series-9")
The patch above not only drops Series-9 cards checks but also
changes logic for Series-6 controllers which leads to controller
hangs/resets under high io load.
So revert to original arc ctrl checks for Series-6 controllers.
