Merge branch 'mlx5e-per-queue-coalescing'

Tariq Toukan says:

====================
mlx5e per-queue coalescing

This patchset adds ethtool per-queue coalescing support for the mlx5e
driver.

The series introduce some changes needed as preparations for the final
patch which adds the support and implements the callbacks.  Main
changes:
- DIM code movements into its own header file.
- Switch to dynamic allocation of the DIM struct in the RQs/SQs.
- Allow coalescing config change without channels reset when possible.
