Ok, thanks for the analysis.

Since we keep coming back to this issue why don't we simply
solve it forever?  Let's make netif_rx() work in all contexts
and get rid of netif_rx_ni().

I think this is the thing to do because this whole netif_rx_ni()
vs. netif_rx() thing was meant to be an optimization of sorts (this
goes back to like 8+ years ago :-), and really I doubt it really
matters on that level any more.

What do you think?
