Assuming you're referring to NET_RX_CN_*, this doesn't seem to be the 
case anymore: it appears netif_rx can only return NET_RX_SUCCESS or 
NET_RX_DROP.

The congestion level constants are hardly used at all - if they are 
left-overs, would it make sense ripping them out completely?

Either way I believe the following should be OK:


Remove inaccurate netif_rx() return value comments.
