From 7a536265b0b470893c13dc0f094e3078521818e2 Mon Sep 17 00:00:00 2001 From: Arik Nemtsov Date: Mon, 10 Feb 2014 13:47:20 +0200 Subject: [PATCH] wlcore: AP: don't start mac80211 PS on non-peer HLIDs It seems the wl18xx FW sometimes sends spurious changes on the PSM state of the broadcast HLID. This causes us to search for a station on a non-peer link and fail, causing warnings in our log. Prevent the driver from considering PSM changes for any non-peer HLIDs.
