Perhaps your test program isn't causing the WSL kernel to hit the 
`net_if_rx_ni_entry`, `net_napi_gro_receive_entry`, and 
`net_if_receive_skb_list_entry tracepoints` during your tracing session?

I recommend using `perf` to double-check that there are indeed none of 
those tracepoints being hit during a tracing session.

thanks,
