 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
