For the entire series:

Tested-by: Thomas Petazzoni <thomas.petazzoni@...e-electrons.com>

tested on:

 * Armada XP DB, DT-based, which uses the mvneta driver. It is affected
   by the 3 first commits since Armada XP also uses the mvmdio driver.

 * Kirkwood development board, non-DT, which uses the mv643xx_eth
   driver.

Thanks Florian for this work,

Thomas
