Message-ID: <55F86158.2090907@candelatech.com> (sfid-20150915_202014_409040_1EED3B12) Date: Tue, 15 Sep 2015 11:20:08 -0700 MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8; format=flowed Sender: linux-wireless-owner@vger.kernel.org List-ID: ath10k firmware allows one to set fixed rates for broadcast, multicast, and management/beacon frames. I think upstream firmware may not have full support, but the API is there in 10.1, at least, and CT firmware has full support. I think the defaults are 6Mbps, but not certain of that. CT kernels have a patch that gives debugfs access to set this, and I am also working on automatically decreasing the rate down to 1Mbps if user has specified only /b legacy rates, etc. Instead of using whatever the firmware chooses for defaults, I think it is better if the driver explicitly set the rates as desired. So, what are the suggested defaults for these rate types? Stick with 6Mbps for /b/g and /a modes? Set to 1Mbps of /b mode? Different defaults for different types? Also, at least some ucast/bcast frames may be turned into directed frames and then it may use normal peer rate-ctrl logic, as far as I remember.
