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.
