From 31b204525a7f0decee85ec336d406c01c5411a5c Mon Sep 17 00:00:00 2001 From: Eyal Shapira Date: Tue, 8 Apr 2014 17:52:27 +0300 Subject: [PATCH] iwlwifi: mvm: rs: revert changes to search cycle rules Adding more options in the search cycle causes longer search cycles with additional wondering off to non optimal Tx configurations.
