So do we know why mpt(4) isn't making use of MSI on FreeBSD? Markus'
original pciconf -lvc output does show MSI and MSI-X capabilities:
mpt0@pci0:134:2:0: class=0x010000 card=0x30601000 chip=0x00501000 rev=0x02 hdr=0x00
vendor = 'LSI Logic (Was: Symbios Logic, NCR)'
device = 'SAS 3000 series, 4-port with 1064 -StorPort'
class = mass storage
subclass = SCSI
cap 01[50] = powerspec 2 supports D0 D1 D2 D3 current D0
cap 05[98] = MSI supports 1 message, 64 bit
cap 07[68] = PCI-X 64-bit supports 133MHz, 2048 burst read, 16 split transactions
cap 11[b0] = MSI-X supports 1 message in map 0x14
