Subject: [PATCH 20/20] net: stmmac: Move MAC Tx/Rx disabling to HW-setup antagonist
Date:   Mon, 8 Feb 2021 17:03:41 +0300
Message-ID: <20210208140341.9271-21-Sergey.Semin@baikalelectronics.ru>
In-Reply-To: <20210208140341.9271-1-Sergey.Semin@baikalelectronics.ru>

Precedence: bulk

Since MAC Tx/Rx activity is enabled in the core hardware setup procedure
it would be logically correct to it disabled in the HW-setup antagonist -
stmmac_hw_teardown(). Let's do that to improve the driver code coherency
and thus readability.
