Improve mdio master read/write by using singe mii read/write lo/hi. In a read and write we need to poll the mdio master regs in a busy loop to check for a specific bit present in the upper half of the reg. We can ignore the other half since it won't contain useful data. This will save an additional useless read for each read and write operation. In a read operation the returned data is present in the mdio master reg lower half. We can ignore the other half since it won't contain useful data. This will save an additional useless read for each read operation. In a read operation it's needed to just set the hi half of the mdio master reg as the lo half will be replaced by the result. This will save an additional useless write for each read operation. Tested-by: Ronald Wahl <ronald.wahl@raritan.com> Signed-off-by: Christian Marangi <ansuelsmth@gmail.com> Signed-off-by: David S.
