Hi How can I use this firewall with other XDP projects?

[2] Raising RLimit...

[0] [WARNING] Failed to attach XDP program to interface 'wlo1' using available modes (1).
[0] [ERROR] Failed to attach XDP program to any configured interfaces.

I need to use this XDP firewall in front of my L4 load balancer. I'm using Facebook's Katran

I'm also looking for something similar to what you're currently experiencing. I have a web server running in the kernel that conflicts with the one used in this project, and I'm quite frustrated by this problem.
