[Agilex]:bridge configuration invalid in PCIe

[raju1421]

Dear Intel Support Team,

We are encountering a problem in our Agilex SOC Development Kit, which is connected to an I210-T1 Ethernet Server Adapter.

Please find the below prints

Hello Raju1421,

Thank you for the update. We have identified that this is more closely related to the FPGA development kits and falls outside the scope of our support.

We will proceed to transfer this thread to the appropriate group to ensure you receive better support accordingly.
