Subject: [RFC v2 2/7] ieee80211: define HT operation CCFS2 field
Date: Tue, 14 Feb 2017 14:22:03 +0100 [thread overview]
Message-ID: <20170214132208.8715-3-johannes@sipsolutions.net> (raw)
In-Reply-To: <20170214132208.8715-1-johannes@sipsolutions.net>
From: Johannes Berg <johannes.berg@intel.com>
The Channel Center Frequency Segment 2 field is used in
802.11-2016 for encoding the actual channel position of
the 80+80/160 MHz channel, if the max NSS is restricted.
This is used for backwards compatibility.
