From: Samuel Ortiz Date: Fri, 19 Dec 2008 02:37:12 +0000 (+0800) Subject: iwl3945: Use iwl-agn-rs.h rates definitions. X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d9829a67f953379b5cab6b78ae8f7a879a591eb1;p=linux-beck.git iwl3945: Use iwl-agn-rs.h rates definitions. A lot of rate relates definition are shared between iwl-3945-rs.h and iwl-agn-rs.h. Let's just use the agn version, and add the 3945 specific constants there.
