Yes, it is a bit ugly. But there is no better way till now, as some of users want to have the functionality of KNI ethtool though limited now.
I have an idea that is to disable KNI ethtool support by default, as most of users may not care about it. Then these users will not be bothered by these type of issues.
For those users who are using KNI ethtool support, they need to fix the issues on any new versions of kernel or similar.
Any good ideas or comments?
