Subject: [PATCH net-next v4 5/7] net: phy: genphy_c45_pma_baset1_read_master_slave: read actual configuration
Date: Fri,  6 May 2022 06:23:55 +0200	[thread overview]
Message-ID: <20220506042357.923026-6-o.rempel@pengutronix.de> (raw)
In-Reply-To: <20220506042357.923026-1-o.rempel@pengutronix.de>

Since MDIO_PMA_PMD_BT1_CTRL register shows actual configuration (and
forced state configuration is equal to the state), we should show
this configuration for ethtool.
