Hi Horatiu
Why do you need these restrictions. The HW bridge should be able to
learn that a
Before when a port was added to a bridge then the port was added in
promisc mode. But because of the patches:
commit 6657c3d812dc5d ("net: Add HW_BRIDGE offload feature")
commit e2e3678c292f9c (net: mscc: Use NETIF_F_HW_BRIDGE")
the port is not needed to be in promisc mode to be part of the
Enable HW_BRIDGE feature for ocelot. In this way the HW will do all the
switching of the frames so it is not needed for the ports to be in promisc
mode.

This patch adds a netdev feature to configure the HW as a switch.
The purpose of this flag is to show that the hardware can do switching
of the frames.
