This configuration make no sense whatsoever.

1) You create a bridge with no ports. What purpose does it serve?
2) If you want to add enp7s0 as a port, why do you have a configuration
for enp7s0? If an interface is a bridge port, it cannot be used for IP
traffic, so assigning it an IP is pointless.
