From d1a1646c0de7b0083d42a1ada72a3ec243bfcc6d Mon Sep 17 00:00:00 2001 From: Arend Van Spriel Date: Fri, 29 May 2020 11:41:43 +0200 Subject: cfg80211: adapt to new channelization of the 6GHz band The 6GHz band does not have regulatory approval yet, but things are moving forward. However, that has led to a change in the channelization of the 6GHz band which has been accepted in the 11ax specification. It also fixes a missing MHZ_TO_KHZ() macro for 6GHz channels while at it. This change is primarily thrown in to discuss how to deal with it. I noticed ath11k adding 6G support with old channelization and ditto for iw. It probably involves changes in hostapd as well.
