mlxsw: spectrum_fid: Store ifindex of NVE device in FID
The driver periodically polls for new FDB entries learned by the device. In the case of an FDB entry learned from a VxLAN tunnel, the notification includes the IP of the remote VTEP, the filtering identifier (FID) and the source MAC address of the overlay packet. Assuming learning is enabled in the VxLAN and bridge drivers, the driver needs to generate a notification and update them about the new FDB entry. Store the ifindex of the NVE device in the FID so that the driver will be able to update the VxLAN and bridge drivers using it.
