Subject: [PATCH 14/16] mt76: mt7915: add .sta_statistics support
Date: Fri, 10 Apr 2020 16:54:51 +0800	[thread overview]
Message-ID: <8e434a52755b926cc88cd0aebce59772e82e2793.1586507878.git.ryder.lee@mediatek.com> (raw)
In-Reply-To: <cover.1586507878.git.ryder.lee@mediatek.com>

Add useful debug counters since this generation uses struct rate_info
to report HE tx rate.
