What is the test setup you are using? So that I can also test I verified the program in this minimal test setup, I did not see any issue with the mac addresses being set.
Below is the test setup.
machine 1 machine 2 (90.0.0.2)port 1 ===============>port3(90.0.0.1) || (80.0.0.2)port 2<================port4(80.0.0.1) traffic gen xdp program
Below are the steps followed to run the program.
Assigned ips in different subnets to interfaces 3 and 4 Ip of port 1 is in the same subnet as port 3 Ip of port 2 is in the same subnet as port 4 sysctl -w net.core.bpf_jit_enable=1 ./xdp_router_ipv4 eth0 eth1
Note: The program will not generate arp requests. Proper arp entries need to be added to get the packets forwarded correctly.
