From 680c15c9eaa0b8b2bdc6df56c29ae27dbae537e0 Mon Sep 17 00:00:00 2001 From: John Crispin Date: Mon, 2 Feb 2015 09:01:44 +0000 Subject: mac80211: Revert adding SM Power Save capability to hostapd configuration Part of rev 44173 added setting the SM Power Save capability in the hostapd.conf file if the driver indicated that it was supported. It appears this was incorrect, because the field in the actual HT Capabilities field in the AP configuration is really a state indication. Just copying the state from the capability resulted in the AP indicating that it had SMPS enabled all the time if it supported SMPS. This effectively just disables all clients from sending packets to the AP with more than one spatial stream, for no good reason. So remove this part of the change.
