So it looks that You don't have specified "tenant_network_types". As "type_drivers" You have enabled "vlan" and "flat" networks so You can create Your network by adding "--provider:network_type=vlan (or flat)".
Or You can add e.g. vxlan to type_drivers option and to tenant_network_types also and then if You not specify "provider:network_type" in Your request, vxlan network will be created.

Of course You can use also other type drivers instead of vxlan if You
want. It's just an example.
