Subject: net: mv643xx_eth: Add missing phy_addr_set in DT mode
From: Jason Gunthorpe <jgunthorpe@xxxxxxxxxxxxxxxxxxxx>
Commit cc9d4598 'net: mv643xx_eth: use of_phy_connect if phy_node
present' made the call to phy_scan optional, if the DT has a link to
the phy node.
However phy_scan has the side effect of calling phy_addr_set, which
writes the phy MDIO address to the ethernet controller. If phy_addr_set
is not called, and the bootloader has not set the correct address then
the driver will fail to function.
Tested on Kirkwood.
