There are not many users of 'uint' in the kernel and it's not used in the stmmac driver so far. From my point of view I would not introduce it and stick to the standard 'unsigned int'.

A mode parameter has been added to the callback function of fix_mac_speed to indicate the physical layer type. The mode can be one the following: MLO_AN_PHY - Conventional PHY MLO_AN_FIXED - Fixed-link mode MLO_AN_INBAND - In-band protocol Also use short version of 'uint' to replace the 'unsigned int' in the function definitions.
