Subject: [PATCH 6/6] mt76: mt7921: reduce the data latency during hw scan
Date: Tue, 6 Apr 2021 11:34:39 +0800	[thread overview]
Message-ID: <2a90d50ed8f1f423d84d02c2d32e9e0686873525.1617679693.git.objelf@gmail.com> (raw)
In-Reply-To: <4c5666ad0683e467f11ca4a4abb5be335be25696.1617679693.git.objelf@gmail.com>

From: Sean Wang <sean.wang@mediatek.com>

Reduce the data latency during hw_scan by the split scan which would switch
back to operational channel right after scanning each channel done.
