Subject: [PATCH net-next 0/5] mlx5e per-queue coalescing

Hi,

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.

Series generated against:
commit fdf412374379 ("gve: Remove qpl_cfg struct since qpl_ids map with queues respectively")

Thanks,
Tariq.
