neutron-l2gateway-agent has an undeclared file conflict.  This may
result in an unpack error from dpkg.

The file /etc/neutron/l2gateway_agent.ini is contained in the packages
 * neutron-l2gateway-agent/1:22.0.0-1 as present in forky|unstable
 * python3-networking-l2gw/1:21.0.0-1 as present in trixie

These packages can be unpacked concurrently, because there is no
relevant Replaces or Conflicts relation.  Attempting to unpack these
packages concurrently results in an unpack error from dpkg, because none
of the packages installs a diversion for the affected file.

Kind regards
