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.

In order to avoid conflicts, this patch-set is rebased over Florian Fainelli's
"[PATCH net-next v2 3/3] net: bcmgenet: Fix coalescing settings handling" patch.

v1: Fix compilation issues due to missed function renaming.

Tal Gilboa (4):
  net/dim: Rename *_get_profile() functions to *_get_rx_moderation()
  net/dim: Add "enabled" field to net_dim struct
  net/dim: Support adaptive TX moderation
  net/mlx5e: Enable adaptive-TX moderation

This doesn't even apply cleanly to net-next, always generate your patch
series against the current state of the GIT tree.

Applying: net/dim: Rename *_get_profile() functions to *_get_rx_moderation()
Applying: net/dim: Add "enabled" field to net_dim struct
