From 403ab56b1c2786b0e1d58c27f5ce667b529c7faa Mon Sep 17 00:00:00 2001 From: Mohamed Abbas Date: Tue, 6 Nov 2007 22:06:25 -0800 Subject: [PATCH] iwl4965: fix cannot find a suitable rate issue This patch fixes the iwl4965 problem for "Can not find a suitable rate issues." by making rs_switch_to_mimo and rs_switch_to_siso functions return -1 when CONFIG_IWL4965_HT is not selected. They used to return 0, which means we can switch to HT rate causing the rate scale problem and the error message. The patch also fix another bug reported by Ben Cahill that it uses wrong value for max_success_limit.
