Subject: [PATCH net-next V3 0/3] Introduce adaptive TX interrupt moderation to net DIM

Net DIM is a library designed for dynamic interrupt moderation. It was
implemented and optimized with receive side interrupts in mind, since these
are usually the CPU expensive ones. This patch-set introduces adaptive transmit
interrupt moderation to net DIM, complete with a usage in the mlx5e driver.
Using adaptive TX behavior would reduce interrupt rate for multiple scenarios.
Furthermore, it is essential for increasing bandwidth on cases where payload
aggregation is required.

v3: Remove "inline" from functions in .c files (requested by DaveM). Revert
adding "enabled" field from struct net_dim and applied mlx5e structural
suggestions (suggested by SaeedM).

v2: Rebase over proper tree.

v1: Fix compilation issues due to missed function renaming.

Tal Gilboa (3):
  net/dim: Rename *_get_profile() functions to *_get_rx_moderation()
  net/dim: Support adaptive TX moderation
  net/mlx5e: Enable adaptive-TX moderation
