[neutron] Use the same network interface with multiple ML2 mechanism drivers

Dear all,

I know that ML2 Neutron core plugin is designed to
support multiple mechanism and type drivers simultaneously.
But I'd like to know: is it possible to use the
same network interface configured with different
ML2 mechanism drivers?

I'm planning to use openvswitch and linuxbridge as
mechanism drivers along with VLAN as type driver.
Could it be possible to have the following
configuration for that purpose?:

mechanism_drivers = openvswitch,linuxbridge
network_vlan_ranges = physnet1:40:60,physnet2:60:80

eth3 is a port of the provider bridge:
ovs-vsctl add-port br-provider eth3

bridge_mappings = physnet1:br-provider

physical_interface_mappings = physnet2:eth3

If it's mandatory to use different network interfaces
any guide or sample reference about implementing
multiple mechanism drivers would be highly appreciated.

Thanks in advance,
Gabriel Gamero
