Subject: [PATCH 2/3] net: dsa: microchip: provide the function ksz_switch_shutdown()
Date: Thu, 9 Sep 2021 11:53:23 +0200 [thread overview]
Message-ID: <20210909095324.12978-3-LinoSanfilippo@gmx.de> (raw)
In-Reply-To: <20210909095324.12978-1-LinoSanfilippo@gmx.de>
Provide a function ksz_switch_shutdown() which properly shuts down the KSZ
switch by stopping the mib_read worker thread and then tearing down the DSA
tree.
