I tested these (2) patches on QDF2400 hardware and saw performance
improvements in line with those I reported when testing the original
series. I don't have any hardware close at hand to test the 3rd patch
in the series so that will have to come from someone else.
Tested-by: Nate Watterson <nwatt...@codeaurora.org>
Thanks,
Nate
