Subject: [wpan-next 14/14] net: mac802154: Introduce a synchronous API for MLME commands
Date: Thu, 20 Jan 2022 01:51:22 +0100	[thread overview]
Message-ID: <20220120005122.309104-15-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20220120005122.309104-1-miquel.raynal@bootlin.com>

This is the slow path, we need to wait for each command to be processed
before continuing so let's introduce an helper which does the
transmission and blocks until it gets notified of its asynchronous
completion. This helper is going to be used when introducing scan
support.
