Specifically about br0 section:

You mention "address" and "netmask" parameters twice.

All bond-* parameters don't belong here, they should be used in the 
section that describes bond0, not br0.
bond-lacp_rate parameter makes sense only for bond mode 4 (aka 802.3ad), 
you seem to be using mode 0 (aka balance-rr).

Not sure it this net.bridge.bridge-nf-call*=0 are needed.

Maybe you are mixing configurations from different reference sources, 
that describes different scenarios?
