This situation simulated from bunch of veths and Bluetooth dis/reconnection.
During qdisc initialization, qdisc was being set to noop

In older kernels, pre batched ops, it returns EINVAL as the arguments
are not supported in the syscall.

In 'bpf_ringbuf_reserve()' we require the flag to '0' at the moment.
For 'bpf_ringbuf_{discard,submit,output}' a flag of '0' might send a
