MSA is an optional extension to MIPSr4 (I think r4 did not exist either, r5 does). Octeon 3 implements r5 but not MSA. It does have the virtualization extension though.
After octeon 3, cavium/marvell is no longer working on MIPS cores. I dont know of any other mainstream source for MIPS cores either.
