   Thanks for working on this.   
      
   Strange thing is that I didn't manage to see the crash on 6.16.0-rc6,   
   6.17.0-rc3 or 6.18.0-rc1 that is the latest. I feel that your   
   environment is hugely different from mine.   
      
   I followed your steps you attached in your code:   
   ////// gcc xskInt.c -lxdp   
   ////// sudo ip link add veth1 type veth   
   ////// sudo ip link set veth0 up   
   ////// sudo ip link set veth1 up   
   ////// sudo ./a.out   
      
   The version of libxdp that I use is 1.4.2, BTW.   
      
   Could you share me with your .config? I'm not sure if I missed something.   
      
   Thanks,   
   Jason
