Hi,
I am using Intel X710 along with FINISAR module (FTLX1471D3BCL). I am trying to read the module's eeprom but I am getting garbage values when DPDK is used. However, it is working perfectly fine when device is bound to the linux kernel. I have attached the device details along with the eeprom dumps. Note that I have executed the command in a VM where Intel X710 was using pci-passthrough. Let me know if more details are required to understand the issue.

I am trying to read the module's eeprom but I am getting garbage values when DPDK is used. However, it is working perfectly fine when device is bound to the linux kernel. I have attached the device details along with the eeprom dumps. Note that I have executed the command in a VM where Intel X710 was using pci-passthrough.
