# Test multiple bridge instances on single eswitch:
# - Create two bridge instances, verify that net devices attached to the same
# bridge can ping each other and that net devices from different bridges can't
# ping each other.
# - Move net device to another bridge and verify connectivity with devices on
# the same bridge instance.
