There still is the problem that there are at least some LSI HBAs that
can be upgraded to MegaRAID but also use the same PCI IDs when that
add-on is not in place. The mpt(4) driver has some initial support
for that in place by returning BUS_PROBE_LOW_PRIORITY for one ID
known so far. However, unlike the corresponding Linux driver,
mfi(4) doesn't try to figure out whether such an HBA actually is in
MegaRAID and attaches instead.
