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

ip link set dev veth1 address 3a:10:5c:53:b3:5c

////// sudo ./a.out

that will do the trick on a recent kerlek....

its the destination mac in the c code....

ps: chaining in the original reporter from the fedora land.....

hi, FWIW I have reproduced this and I bisected it, issue was introduced
at 30f241fcf52aaaef7ac16e66530faa11be78a865 - working on a patch.

Exactly. I simply reverted it and its dependencies and didn't see any
crash then. It was newly introduced, hopefully it will not bring much
trouble. As I replied before, I will take a look tomorrow morning.

Thanks,
Jason
