No, mpt fusion is not for megaraid controllers. The megasr driver is the "software raid" driver stack over mpt fusion controller, which is closed source, you should contact the megaraid team to get the entire driver. The megaraid team also have their own bios to be used with these controllers, this bios will create a default raid volume when no one is present, thus corrupting the data, hense you don't want to use the mpt fusion drivers for that megaraid controller. The megasas driver is full hardware raid solution, like raid levels 0, 1, 5, 6, 10, 50, and 60.
