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!

Changelog
=====
v4->v5:
  - Update some snippets from Kuba, Thanks.

v3->v4:
  - Some tiny updates and patch 1 only add a new comment.

v2->v3:
  - Break up the attributes to avoid the use of raw c structs.
  - Use per-device profile instead of global profile in the driver.

v1->v2:
  - Use ethtool tool instead of net-sysfs
