Subject: [PATCH] ath10k: set a-mpdu reference number in ath10k (receiver)
Date: Wed, 5 Jul 2017 20:34:10 +0200	[thread overview]
Message-ID: <B8D63297-0A88-42A3-B789-3849895CF201@frei.media> (raw)

Set the a-mpdu reference number in ath10k to make it accessible in the receivers radiotap header. Implemented as in ath9k. 
The reference number is needed for troubleshooting and research at the receivers site (e.g. to identify mpdu's that were aggregated in an a-mpdu)
