Public bug reported:

DB plugin checks for network existence during port create:
https://github.com/openstack/neutron/blob/cb64e3a19fdddb3eac593114a482c9dd69be68d5/neutron/db/db_base_plugin_v2.py#L1422

There is no need to fetch the whole net object (which leads to several
heavy DB requests according to OSProfiler stats) when only need to check
net existence.
