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?
