From 5bbe233b9bafabc08a5404d54b9fa086e8390fc7 Mon Sep 17 00:00:00 2001 From: Abhijeet Kolekar Date: Wed, 8 Apr 2009 11:26:35 -0700 Subject: iwl3945: use iwl_bss_info_changed 3945 can use iwl_bss_info_changed. A new lib op is created for post_assoicate to distinguish between 3945 and iwlwifi's post_associate operations. Signed-off-by: Abhijeet Kolekar Signed-off-by: Reinette Chatre Signed-off-by: John W.
