Subject: [PATCH net-next 0/4] 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.

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
