-Subject: [PATCH] net: dsa: qca8k: clear MASTER_EN after phy read/write
-
-Clear MDIO_MASTER_EN bit from MDIO_MASTER_CTRL after read/write
-operation. The MDIO_MASTER_EN bit is not reset after read/write
-operation and the next operation can be wrongly interpreted by the
-switch as a mdio operation. This cause a production of wrong/garbage
-data from the switch and underfined bheavior. (random port drop,
-unplugged port flagged with link up, wrong port speed)
-Also on driver remove the MASTER_CTRL can be left set and cause the
-malfunction of any next driver using the mdio device.
