-Subject: [PATCH] enetc: Set MDIO_CFG_HOLD to the recommended value of 2
-
-This increases the MDIO hold time to 5 enet_clk cycles from the previous
-value of 0. This is actually the out-of-reset value, that the driver was
-previously overwriting with 0. Zero worked for the external MDIO, but
-breaks communication with the internal MDIO buses on which the PCS of
-ENETC SI's and Felix switch are found.
