[abdhaleegit]

Problem:

bootlist fails to translate the OF device to logical interface name for Mellanox net devices with single pci bus per 2 ports

# bootlist -m normal -o
Could not translate /pci@800000020000106/pci15b3,1007@0 to logical device name
Could not translate /pci@800000020000106/pci15b3,1007@0 to logical device name

Machine: Power 9 PowerVM LPAR
Distribution: All distribution
Card Type: all Mellanox cards of type ConnectX-3
powerpc-utils latest version: upstream

---Steps to Reproduce---

1. Attach a Mellanox ConnectX-3 card to LPAR

2. Build and install the latest utils git clone https://github.com/ibm-power-utilities/powerpc-utils.git

3. Check the boot configurations

4. List the logical device names

# bootlist -m normal -o
sda
net0

5. display OF names

# bootlist -m service -r
/vdevice/l-lan@30000002:speed=auto,duplex=auto,9.3.80.16,,9.53.171.172,9.53.168.1,5,5,255.255.252.0,512

6. set the boot configuration for the 2 mellanox interfaces enP262p160s0 and enP262p160s0d1 wich has single pci bus 0106:a0:00.0
   # bootlist -m normal enP262p160s0 enP262p160s0d1 net0 /dev/sda
7. Check the configurations now

# bootlist -m normal -o
Could not translate /pci@800000020000106/pci15b3,1007@0 to logical device name
Could not translate /pci@800000020000106/pci15b3,1007@0 to logical device name
net0
sda

# bootlist -m service -r
/vdevice/l-lan@30000002:speed=auto,duplex=auto,9.3.80.16,,9.53.171.172,9.53.168.1,5,5,255.255.252.0,512

You can see the bootlist fails to translate the OF device to logical interface name with above error

Also at SMS menu you can see the boot configuration for is not set for enP262p160s0 and enP262p160s0d1 interfaces

@tyreld please have a look

It would help to have the device tree output as well.
