From 815b8092bd5242d580038213da9179a5a4f69116 Mon Sep 17 00:00:00 2001 From: Marco Porsch Date: Wed, 5 Dec 2012 15:04:26 -0800 Subject: [PATCH] mac80211: don't drop mesh peering frames from unknown STA Previously, mesh peering frames from a STA without a station entry were being dropped. Mesh Peering Open and other frames (WLAN_CATEGORY_SELF_PROTECTED) are valid mesh peering frames even if received from a yet unknown station; the STA entry will be created in mesh_peer_init later. The problem didn't occur previously since both STAs receive each other's beacons which created the STA entry. However, this causes an unnecessary delay and beacons might not be received if either node is in PS mode.
