Subject: [PATCH net-next 06/17] net: dsa: Call driver's setup callback after setting up its switchdev notifier

This allows the driver to perform some manipulations of its own during
setup, using generic code.
One current usage scenario is for the driver to request DSA to set up
802.1Q based switch tagging for its ports.
