This should be a mrsas card and not an HBA!  mrsas supports all current
UCS RAID cards ... and the next unreleased UCS system :-)  You might need
the one in -current for that.  I'm not sure what is in 12.1.

Hi Doug!  Thanks.  Okay, I infer from that that the mpr driver is for
HBAs that aren't raid?  Grepping through the sources for 3516 found me
only mpr.  Looking more carefully, at mrsas while knowing specifically
what I'm looking for, I find the PCI device ID (0x0014) as "AVAGO
Ventura
SAS Controller".  And, that code (mrsas) is about the same in stable-12 as
is it in -current.

Can you provide some guidance of what I need to do to get the mrsas
driver to identify it when booting the install ISO?
