I backported the mpt driver from -STABLE to 4.6-RELEASE, and it is 
recognized correctly:

mpt0: <LSILogic 1030 Ultra4 Adapter> port 0xdc00-0xdcff mem 
0xff6a0000-0xff6bffff,0xff6c0000-0xff6dffff irq 18 at device 12.0 on pci3
mpt1: <LSILogic 1030 Ultra4 Adapter> port 0xd800-0xd8ff mem 
0xff660000-0xff67ffff,0xff680000-0xff69ffff irq 19 at device 12.1 on pci3

However, my drives aren't attached as Ultra-320 but at much lower speeds:

da0 at mpt1 bus 0 target 0 lun 0
da0: <SEAGATE ST336732LW 2223> Fixed Direct Access SCSI-3 device
da0: 62.500MB/s transfers (31.250MHz, offset 31, 16bit), Tagged Queueing 
Enabled
da0: 34732MB (71132959 512 byte sectors: 255H 63S/T 4427C)
da1 at mpt1 bus 0 target 1 lun 0
da1: <SEAGATE ST336732LW 2223> Fixed Direct Access SCSI-3 device
da1: 62.500MB/s transfers (31.250MHz, offset 31, 16bit), Tagged Queueing 
Enabled
da1: 34732MB (71132959 512 byte sectors: 255H 63S/T 4427C)

When I hook them up to the Ultra-160 onboard Adaptec chip, things look 
better:

ahc0: <Adaptec aic7892 Ultra160 SCSI adapter> port 0xd400-0xd4ff mem 
0xff6fe000-0xff6fefff irq 14 at device 14.0 on pci3
aic7892: Ultra160 Wide Channel A, SCSI Id=7, 32/253 SCBs
...
da0 at ahc0 bus 0 target 0 lun 0
da0: <SEAGATE ST336732LW 2223> Fixed Direct Access SCSI-3 device
da0: 160.000MB/s transfers (80.000MHz, offset 63, 16bit), Tagged 
Queueing Enabled
da0: 34732MB (71132959 512 byte sectors: 255H 63S/T 4427C)
da1 at ahc0 bus 0 target 1 lun 0
da1: <SEAGATE ST336732LW 2223> Fixed Direct Access SCSI-3 device
da1: 160.000MB/s transfers (80.000MHz, offset 63, 16bit), Tagged 
Queueing Enabled
da1: 34732MB (71132959 512 byte sectors: 255H 63S/T 4427C)

Any ideas on how to make mpt use Ultra-320 to talk to the drives?

Thanks,
Lars
