Merge branch 'net-create-dynamic-software-irq-moderation-library'
Andy Gospodarek says:
====================
net: create dynamic software irq moderation library
This converts the dynamic interrupt moderation library from the mlx5e
driver into a library so it can be used by any driver. The penultimate
patch in this set adds support for this new dynamic interrupt moderation
library in the bnxt_en driver and the last patch creates an entry in the
MAINTAINERS file for this library.
The main purpose of this code is to allow an administrator to make sure
that default coalesce settings are optimized for low latency, but
quickly adapt to handle high throughput/bulk traffic by altering how
much time passes before popping an interrupt.
For any new driver the following changes would be needed to use this
library:
- add elements in ring struct to track items needed by this library
- create function that can be called to actually set coalesce settings
for the driver
Credit to Rob Rice and Lee Reed for doing some of the initial proof of
concept and testing for this patch and Tal Gilboa and Or Gerlitz for
their comments, etc on this set.
v4: Fix build breakage for VF representers noticed by kbuild test robot.
Thanks for being so courteous, kbuild test robot!
v3: bnxt_en fix from Michael Chan, comment suggestion from Vasundhara
Volam, and small mlx5e header file fix from Tal Gilboa.
v2: Spelling fixes from Stephen Hemminger, bnxt_en suggestions from
Michael Chan, spelling and formatting fixes from Or Gerlitz, and
spelling and mlx5e changes suggested by Tal Gilboa.
