I'm not sure about this. After all I can send as much data over
network as I can and the receiver might have not enough resources to
handle it. Isn't receiver the one that should worry about
congestion?
I might not say it clearly, but my driver is sending only raw Ethernet
frames. No TCP/IP. As you can see, it's very basic communication. Yet I
would be happy to know when device driver is dropping packets.
As I said, there used to be queue's cng_level struct member in netif_rx.
It contained information about ingress traffic queue congestion level.
But now it's gone and I can't figure out what else to use.
