With this patch, ice driver is able to track if the port representors or uplink port were added to the linux bridge in switchdev mode. Listen for NETDEV_CHANGEUPPER events in order to detect this. ice_esw_br data structure reflects the linux bridge and stores all the ports of the bridge (ice_esw_br_port) in xarray, it's created when the first port is added to the bridge and freed once the last port is removed. Note that only one bridge is supported per eswitch. Bridge port (ice_esw_br_port) can be either a VF port representor port or uplink port (ice_esw_br_port_type). In both cases bridge port holds a reference to the VSI, VF's VSI in case of the PR and uplink VSI in case of the uplink. VSI's index is used as an index to the xarray in which ports are stored. Add a check which prevents configuring switchdev mode if uplink is already added to any bridge. This is needed because we need to listen for NETDEV_CHANGEUPPER events to record if the uplink was added to the bridge. Netdevice notifier is registered after eswitch mode is changed to switchdev.
