This repo explains how to unlock X710 to accept any SFP module. Symptom by connecting non-intel SFP module:
i40e 0000:04:00.1: Rx/Tx is disabled on this device because an unsupported SFP module type was detected.
i40e 0000:04:00.1: Refer to the Intel(R) Ethernet Adapters and Devices User Guide for a list of supported modules.
This tool was tested on X710-DA2 card.
Use intel NVM utility to upgrade firmware. I was using nvmupdatepackage_v9_10 and upgraded x710-2DA to 9.10 firmware.
First tool to use is mytool.c. Replace FILL_ME_IN with correct values, build and read eeprom to file:
./mytool 0 0x8000 > eeprom.txt
Open eeprom.txt and find 4 values 000b: it should be in around range of 0x6800-0x7000 and offset between 000b values should be around 0xb-0xf.
In my case 000b was at 0x6948 and offset between values 0xf.
It seems that the important register is floating around in eeprom. Basically it should be:
- 11 bit enabled register value
- The same offset from the
000bvalue. - 4 identical register values
In my case it was 0x1 form 000b value, at: 0x6948, 0x6956, 0x6964, 0x6972. The value was 0x6b0c.
Replace FILL_ME_IN with gathered values, build and run.
After successful poke, reboot the machine.
