[dpdk-dev] Potential deadlock in KNI RX path

Over a year ago, Neil pointed out that calling netif_rx() from
kni_net_rx_normal() was a bug and could cause lockups. Here's the comment:

Looking at the current code base, it is still calling netif_rx() instead of
netif_rx_ni() as suggested.

Did that fall through the cracks or is there disagreement about whether it
was the right thing to do?

Thanks,
Jay
