From 76f3915b4cbadf5f7dc80d3df6d3a7492914675a Mon Sep 17 00:00:00 2001 From: Gregory Greenman Date: Wed, 23 Jan 2008 10:15:21 -0800 Subject: iwlwifi: Fix uCode error on association The problem is that priv->assoc_id is set when assoc. resp frame is received. But, when it is set, LQ cmd is still not sent to the uCode, it is done from bg_post_assoc, which is called through a workqueue. On the other hand, when a tx arrives at the moment when this flag is set, but LQ is still not sent, the if condition in tx_skb will not hold and the frame will not be dropped. Thus, it will be sent through which is still not in the sta table in the uCoded. Signed-off-by: Gregory Greenman Signed-off-by: Tomas Winkler Signed-off-by: John W. Linville Signed-off-by: David S.
