From: Thomas Pedersen Date: Tue, 22 Sep 2020 02:28:10 +0000 (-0700) Subject: mac80211: encode listen interval for S1G X-Git-Url: https://jxself.org/git/?a=commitdiff_plain;h=62bfcd9040cf8358588a8cd97d037386b49d707f;p=carl9170fw.git mac80211: encode listen interval for S1G S1G allows listen interval up to 2^14 * 10000 beacon intervals. In order to do this listen interval needs a scaling factor applied to the lower 14 bits. Calculate this and properly encode the listen interval for S1G STAs. See IEEE802.11ah-2016 Table 9-44a for reference.
