+This patch fix the problem
+1- Take care of iwl4965: Can not find a suitable rate issues.
+you get this messages because if you build without HT enables
+rs_switch_to_mimo and rs_switch_to_siso functions will always return 0 which
+main we can switch to HT rate causing the rate scale problem and the 
+error message.
+The fix will return -1 default
+
+2- the other fix was reported by Ben Cahil, using wrong value for 
+max_success_limit
