Subject: [PATCH v1 3/5] Bluetooth: advmon offload MSFT remove monitor
Date: Thu,  3 Dec 2020 18:29:33 +0800	[thread overview]
Message-ID: <20201203182903.v1.3.I2bdb3d9953a91dc7865da6e57166260b3a75c146@changeid> (raw)
In-Reply-To: <20201203102936.4049556-1-apusaka@google.com>

From: Archie Pusaka <apusaka@chromium.org>

Implements the monitor removal functionality for advertising monitor
offloading to MSFT controllers. Supply handle = 0 to remove all
monitors.
