From 1ce3e82b0eb472161313183be0033e46d5c4bbaf Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 1 Aug 2012 17:00:55 +0200 Subject: cfg80211: add ieee80211_operating_class_to_band This function converts a (global only!) operating class to an internal band identifier. This will be needed for extended channel switch support.
