+CHANGES WITH 235:

+ * modprobe.d drop-in is now shipped by default that sets bonding module
+ option max_bonds=0. This overrides the kernel default, to avoid
+ conflicts and ambigiuty as to whether or not bond0 should be managed
+ by networkd or not. This resolves multiple bugs of bond0 properties
+ not being applied, when bond0 is configured with
+ networkd. Distributors may choose to not package this, however in
+ that case users will be prevented from correctly managing bond0
+ interface using networkd.

It's a good idea to disable the implicit creation of networking bonding
devices by the kernel networking bonding module, so that the
automatically created "bond0" interface doesn't conflict with any such
