I want to use packets having size more than 1500 bytes, so I want to increase MTU, but when I am increasing MTU xdp is not working, any setting I...
I am trying to write AF_XDP program for passing only packets having specific udp port with bpf_redirect_map, but sometimes no packets are coming to AF_XDP socket. My sender and receiver...
