This patch modifies the sunxi-dev/bananapi-r1-switch-driver.patch to work with
the changed phy/mdio interface in 4.5.
It was also necessary to revert commit
88f8b1bb41c6208f81b6a480244533ded7b59493 "stmmac: Fix 'eth0: No PHY found' regression"
because it breaks networking on all my sun7i-a20 boards (bananapi, cubietruck, and bananapi-r1)

Subject: [PATCH] bananapi-r1 switch driver: Modifications for Kernel v4.5
