From bee488dbd7effea4c4a483b0a336df331066bb3c Mon Sep 17 00:00:00 2001 From: mabbas Date: Thu, 25 Oct 2007 17:15:42 +0800 Subject: [PATCH] iwl4965: exclude 60M rate from probe request This patch do the following 2 things: 1. Make sure we don't add rate 60M part of supported rate in proble request, some AP does not like that. 2. It is wrong to set priv->active_rate in this function, this will set it to all avialable rates which might overwrite the mode supported rate. priv->active_rate should be set by only from iwl_set_rate.
