The following is tempor
Hi,
Is there any way to run this eBPF program without that patch?
Alternatively, is there any other eBPF sample that does run properly?

Hi
I'm trying to run this eBPF program:
https://git.kernel.org/pub/scm/linux/kernel/git/shemminger/iproute2.git/tree/examples/bpf
and I get this error:
:~/iproute2/examples/bpf$sudo tc filter add dev enx00e11100329b parent
1: bpf obj bpf.o exp /tmp/bpf-uds flowid 1:1 action bpf obj bpf.o sec
