How can I change all the device IDs on my quad port Intel NIC?

Thanks So I have a quadport Intel gigabite NIC (dual 82571EB).

To get the device IDs, I used:

lspci - -vvv | grep Etheet

all the 4 devices were identified as 8086:10bc. I want to change 10bc to 105e for all 4 devices.

ifconfig shows all 4 devices as:

enp3s0f0 enp3s0f1 enp4s0f0 enp4s0f1

To find the correct offset, I used this command:

# ethtool -e my-interface-here | grep 86

0x0010 87 d9 05 71 2f 24 4b 70 3c 10 bc 10 86 80 65 b3

Ruing the command above for all 4 interfaces gave me the same result.

I made a backup of the EEPROM for all interfaces using:

ethtool -e my-interface-here raw on > my-interface-here.bin

To actually make the change, I used this command:

ethtool -E enp3s0f0 magic 0x10bc8086 offset 0x001a value 0x001a value 0x5e

Observations/issues:

1. After ruing the ethtool -E command above, it somehow changed the value (using ethtool -e to check) for *both** enp3s0f0 and enp3s0f1

2. I tried the ethtool -E command but for enp3s0f1 and it gave me an error. says "EEPROM bad address" or something along those lines.

3. Basically same as points 1 and 2 but substituting enp4 for all mentions of enp3.

4. After rebooting machine, I ran lspci - -vvv | grep Etheet and it shows only 2 device IDs have changed.

5. I moved the network cable to all 4 ports and I can browse the inteet without any problems. This happened after point 4.

Any suggestions on how to change all device IDs to 105e? thanks
