net: dsa: microchip: Make MDIO bus name unique
In configurations with 2 or more DSA clusters it will fail to allocate unique MDIO bus names as only the switch ID is used, fix this by using a combination of the tree ID and switch ID when needed Signed-off-by: Jesse Van Gavere <jesse.vangavere@scioteq.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Link: https://patch.msgid.link/20241206204202.649912-1-jesse.vangavere@scioteq.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
