From 556f8db74809a435195c840f495fd1bf855dfadb Mon Sep 17 00:00:00 2001 From: Zhu Yi Date: Thu, 27 Sep 2007 11:27:33 +0800 Subject: [PATCH] [PATCH] iwlwifi: clear station table in rxon unconditionally This patch clears stations table for every rxon command. It removes iwl_rxon_add_station function in 3945. Signed-off-by: Tomas Winkler Signed-off-by: Zhu Yi Signed-off-by: John W.
