Back when the mpt3sas driver was first posted I suggested that it should
be merged into mpt2sas, but my proposal didn't get much traction.
Illumos has now produced a shared driver and shown that the difference
are basically limited to a different S/G list format [1], and a quick
experiment on the Linux drivers confirms this mostly - the additional
differences are various smaller workarounds for specific hardware
revisions.
I think we'd all be served much better with a merged driver.

Please. Pretty please.
I've started a merge myself, but then never found time to finalize it.
Carrying three basically identical drivers just creates a
maintenance overhead for everyone involved.
The original idea of splitting the driver and just maintaining the
latest has never really worked out; all fixes to the latest driver
turned out to be applicable to the others, too.
So it just increased the workload for the maintainer for no real
gain. I would _strongly_ vote for it.
Cheers,
Hannes
