When running "ethtool eth0",
I get a line in the output that states -> Supported pause frame use: No
- Does this mean my Ethernet card does not support flow control at all?
I try to enable the flow control with "ethtool -A eth0 rx on tx on",
Nothing happens, the command executes but then "ethtool -a eth0" still reports that it is off
Auto negotiation appears on, but I am unsure if this effects flow control. From what I see, it can determine link flow control?
I question ethtool because when looking online at the specs of my Ethernet card, it looks like it fully supports flow control?
Lastly, I am hooked to a layer 2 switch. Does auto-negotiate have to be on for both endpoints to determine flow control?
All in all, I just want to enable flow control on a host and a switch
