According to the implementation, netif_rx() can fail.
It doesn't exactly "fail", but it does give return values
which indicate RX congestion.
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.
