Previously the bonding driver would create an initial `bond0` interface when it was loaded. If the network management integration used that interface and did not recreate it, it was stuck to the default `balance-rr` mode. Deploying systemds modprobe.d configuration sets `max_bonds=0`, so we don't run into that issue anymore. Hence we now make sure that we can indeed create `bond0` with `802.3ad` (LACP), which is a non default mode.
