[PATCH net-next 16/16] net: Remove switchdev_ops

From: Florian Fainelli
Date: Fri Feb 08 2019 - 19:34:24 EST

Now that we have converted all possible callers to using a switchdev
notifier for attributes we do not have a need for implementing
switchdev_ops anymore, and this can be removed from all drivers the
net_device structure.
