The NetDIM library provides excellent acceleration for many modern
network cards. However, the default profiles of DIM limits its maximum
capabilities for different NICs, so providing a channel through which
the NIC can be custom configured is necessary.

Please review, thank you very much!

Given that DIM is currently enabled and disable via ethtool
why are you putting the API is sysfs and ops in ndo?

Hi Jakub,

Thank you for reaching out. We're flexible regarding configuration 
methods and are
open to using either sysfs or ethtool, depending on what's most 
appropriate for the task at hand.

If the ethtool is favored, I am happy to proceed with it!

Best regards,
Heng
