From 3459ab5a1c92eaf8b76e9fa1b6ca529cf83066f3 Mon Sep 17 00:00:00 2001 From: Reinette Chatre Date: Fri, 22 Jan 2010 14:22:49 -0800 Subject: [PATCH] iwlwifi: make broadcast station addition generic Add function pointer for broadcast station addition so that we can call it in from iwlcore at a later time. We only distinguish between iwlagn and iwl3945 broadcast station addition. For the iwl3945 station addition we add that function to iwlcore since that is where most station functionality resides, making it part of iwl3945 will require significant code reorganization that will dilute station management functionality. This seems to be an efficient solution. It may seem as though we are removing error checking when adding the 3945 broadcast station but this error checking was never really necessary since the function returns the station id and the broadcast station id is always set.
