Continuing without mounted eBPF fs. Too old kernel?

Could it be a kernel configuration issue?

I can't imagine your setup at all.

• Is some pc involved, as you're seeing output?
• Does the Xilinx board have the Aarch64 cpu?
• What are you trying to run xdp on, and why? Can't you use another protocol?
• What are you trying to achieve here?
• Is this your university project?
• Which system (xilinx board or supervisory pc) has the offending network card?
• Does the kernel even support xdp?
