From 085fbca29d7b4574c4e42189ee5789004e4beff7 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 4 Oct 2010 05:47:23 -0700 Subject: iwlwifi: allow probe-after-rx on 2.4 GHz There are two passive 2.4 GHz channels: 12 and 13. If you have a hidden SSID on those, you will not be able to connect to it because we don't send out probe requests there. We can allow this by using the firmware's probe-after-rx functionality on those channels as well.
