From 6ccbb92ead9379d7de2cc25cd950d15a8d22e0c9 Mon Sep 17 00:00:00 2001 From: Juuso Oikarinen Date: Fri, 26 Mar 2010 12:53:23 +0200 Subject: wl1271: Disable connection monitoring while not associated The wl1271 does not support disabling the connection monitor feature. Perform the next best thing by increasing the beacon-loss threshold and BSS_LOSE event timeout to the maximum values. This is needed, because we really don't want any random probe-requests during scanning or especially while in ad-hoc mode and not beaconing.
