Subject: [PATCH net-next v5 0/4] ethtool: provide the dim profile fine-tuning channel
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 way which the NIC can
be custom configured is necessary.
Currently, interaction with the driver is still based on the commonly
used "ethtool -C". The driver declares its supported parameters based
on .supported_coalesce_params, and implements driver-related custom
restrictions in .set_coalesce and .get_coalesce.
Please review, thank you very much!
