Configuring Minstrel-Blues

Configuring Minstrel-Blues

[Mike Mu]

Hi Linux-Wireless,

I am trying to enable Minstrel-Blues for the ath9k chipset that's used
in Google Fiber's access points. I applied the patches in
https://github.com/thuehn/Minstrel-Blues/tree/master/src onto our
backports-20160122 tree, with some unsuspicious merge conflicts, and
built an image.

To test, I ran iperf from the AP to a station very close by. I
captured the packets to look at the RSSI with and without the
Minstrel-Blues patches applied, but did not see any difference in
RSSI.

Is there anything I need to configure first to make it work? Is it
possible that I'm missing a patch that's not in backports-20160122?

Thanks!
Mike

why do you think that a rate control algorithm will change the rssi?

Hi Mike,

I am working on the Minstrel-Blues part to get it integrated into minstrel_ht. My working demo is with ath5k an legacy minstrel.
As soon as I have a testing patch, I am going to announce it here.

Greetings from Berlin
Thomas
