Workaround:
# remove wpi driver
rem_drv wpi
# use pcitool to point to correct device
pcitool /pci@0,0 -d bdf=0.1c.1,config -o 0x20 -s 4 -w 0xd010d010
pcitool /pci@0,0 -d bdf=0.1c.1,config -o 4 -s 1 -w 0x46
pcitool /pci@0,0 -d bdf=3.0.0,config -o 4 -s 1 -w 0x46
pcitool /pci@0,0 -d bdf=3.0.0,config -o 0x10 -s 4 -w 0xd0100000
# add wpi driver:
add_drv -i '"pci8086,4222"' wpi
