def uncfg_intf(self, intf):
pass<EOL>
Called by application to remove an interface to the list.

        From an applications perspective, it makes sense to have this function.
        But, here no action can be taken for the following reasons, but just
        having it as a place-holder for tomorrow.
        => Can't remove interface from the list since DB in server may appear
        stale. self.intf_list.remove(intf)
        => One can just remove the interface DB, but need to retry that till
        it succeeds, so it has to be in periodic loop.
        => So, currently leaving it as is, since LLDP frames won't be obtained
        over the bridge, the periodic handler will automatically remove the
        DB for this interface from server
