Subject: [PATCH 01/25] iwlwifi: mvm: expose device timestamp in radiotap
Date: Tue, 24 Jan 2017 00:03:26 +0200	[thread overview]
Message-ID: <20170123220350.25305-2-luca@coelho.fi> (raw)
In-Reply-To: <20170123220350.25305-1-luca@coelho.fi>

From: Johannes Berg <johannes.berg@intel.com>

Set the relevant fields to export the 32-bit device timestamp to
radiotap using the new mac80211 infrastructure. This will be useful
to allow synchronising monitor captures taken on different hardware
simultaneously.
