From 4ee73f338a528f44fd90496adfbfd9c119401850 Mon Sep 17 00:00:00 2001 From: Michal Kazior Date: Wed, 11 Apr 2012 08:47:56 +0200 Subject: mac80211: remove hw.conf.channel usage where possible Removes hw.conf.channel usage from the following functions: * ieee80211_mandatory_rates * ieee80211_sta_get_rates * ieee80211_frame_duration * ieee80211_rts_duration * ieee80211_ctstoself_duration This is in preparation for multi-channel operation.
