This patch introduces the proto_down flag that can be used by user space
applications to notify switch drivers that errors have been detected on the
device.
The switch driver can react to protodown notification by doing a phys down
on the associated switch port.

protodown can be set by user space applications like MLAG on detecting
errors on a switch port. This patch provides sample switch driver changes
for handling protodown. Rocker PHYS disables the port in response to
protodown.

User space daemons can detect errors in the network that need to be
notified to the switch device drivers.
Drivers can react to this error state by doing a phy-down on the
switch-port which would result in a carrier-off locally and on the directly
connected switch. Doing

This patch adds support to set and display protodown on a switch port. The
switch driver can handle this error state by doing a phys down on the port.
One example user space application setting this flag is a multi-chassis
LAG application to handle split-brain situation

A nested attribute has been added allowing apps to update bits
(IF_PROTOF_DOWN) in the proto_flags field.

On detecting errors an application can set IFF_PROTO_DOWN on a device.
These switchdev APIs allow the switch device driver to react to
IFF_PROTO_DOWN by doing a phy down on the switch port. Doing this allows
the connected server to react quickly and prevent traffic black
