package/kernel/mac80211/patches/904-wlcore-AP-don-t-start-mac80211-PS-on-non-peer-HLIDs.patch

   1 It seems the wl18xx FW sometimes sends spurious changes on the PSM state
   2 of the broadcast HLID. This causes us to search for a station on a
   3 non-peer link and fail, causing warnings in our log.
   4
   5 Prevent the driver from considering PSM changes for any non-peer HLIDs.
