From 9cf0a0b4b64ae103cf0e7dfaa72b44ecda24c0eb Mon Sep 17 00:00:00 2001 From: Alexei Avshalom Lazar Date: Mon, 13 Aug 2018 15:33:00 +0300 Subject: [PATCH] cfg80211: Add support for 60GHz band channels 5 and 6 The current support in the 60GHz band is for channels 1-4. Add support for channels 5 and 6. This requires enlarging ieee80211_channel.center_freq from u16 to u32.
