Description Vishal Deep Ajmera 2020-11-18 10:10:08 UTC 
Description of problem:
Currently nmstate does not support configuring 'ethtool -A' or pause settings on an interface. It instead rely on auto-negotiation to take care of that. However optical links/transceivers does not support auto-negotiation.

Support is needed to configure pause settings on interfaces via nmstate.

Comment 1 Gris Ge 2020-11-19 02:23:26 UTC 
NetworkManager feature request created at bug 1899372 for applying the setting.
Nispor feature request created at bug 1899373 for querying from kernel.

Both of them are targeting RHEL 8.5 and pending approval.

Hi Vishal Deep Ajmera,

Any more detail on how you use nmstate in your environment?
So that our QE could mimic your use case in our tests.

Comment 14 Mingyu Shi 2021-06-06 15:59:19 UTC 
Verified with versions:
nmstate-1.1.0-0.1.el8.noarch
nispor-1.1.0-1.el8.x86_64
NetworkManager-1.32.0-0.4.el8.x86_64

Please check the attachment `verified.log` for details:
1. nmstate reports the correct pause state(ethtool -a)
2. Given a property, if ethtool can change, nmstate can change too.
