The ocelot switch has been supporting LAG offload since its initial commit, however felix could not make use of that, due to lack of a LAG abstraction in DSA. Now that we have that, let's forward DSA's calls towards the ocelot library, who will deal with setting up the bonding. Note that ocelot_port_lag_leave can return an error due to memory allocation but we are currently ignoring that, because the DSA method returns void.
