Reajjy New to Linux

I ran the ethtool -a and this was my output. I have already confirmed...I have the latest ethtool installed

Pause parameters for wlo1:
Cannot get device pause settings: Operation not supported

What are you trying to do ? Try to make the title clearer and to tell what you are trying to do and what you expected from this command.

On my laptop:

Code:

$ ethtool -a enp0s25

Pause parameters for enp0s25:

Autonegotiate:  on

RX:            on

TX:            on



$ ethtool -a wlp3s0

Pause parameters for wlp3s0:

Cannot get device pause settings: Operation not supported

enp0s25 is the wired interface, wlp3s0 the wireless one. I conclude that some or all wireless interfaces don't have pause settings.

EDIT: I guess wireless interfaces don't count as Ethernet interfaces, so that ethtool is probably not the right tool to use anyway.

I just tried

Code:

ethtool -a enp2s0

which is a wired connection and I got the same error as OP. So it seems to be h/w specific.
Later I tried it on two different PC's running Slackware and Mint (wired and wireless), and I got the same errors as OP both times! So not sure what the command is supposed to do!

As far as I understand it, ethtool can set (ethtool -A) flow control on the interface, and report the setting (ethtool -a). I found this quick explanation.

My guess is that not all interfaces or all drivers support this feature.
