From c33104f0a782a7746e5d3b975288a4fb3b8293ed Mon Sep 17 00:00:00 2001 From: Tomas Winkler Date: Mon, 14 Jan 2008 17:46:21 -0800 Subject: [PATCH] iwlwifi: 4965 unify rate scale variable names for station data 1, This patch renames iwl4965_rate_scale_priv to iwl4965_lq_sta. This type represents a station's link quality. 2. The names of the variables of this type were rs_priv, lq_data, lq, crl across the file. All are now unified under the name lq_sta.
