gamemann / XDP-Firewall

A firewall that utilizes the Linux kernel's XDP hook. The XDP hook allows for very fast network processing on Linux systems. This is great for dropping malicious traffic from a (D)DoS attack. IPv6 is supported with this firewall! I hope this helps network engineers/programmers interested in utilizing XDP!

Is that correctly working? should I ignore these above?

Hey, I apologize for the long delay (I've been really busy recently)! The warnings/errors above can be ignored, it just has to do with the XDP Dispatcher from xdp-tools trying to load a xdp_pass XDP test program.

When I have the time, I will look into skipping this test in the future.
