This bug tracker is for errors with the documentation, use the following
as a template and remove or add fields as you see fit. Convert [ ] into
[x] to check boxes:

- [X] This doc is inaccurate in this way: Using self-service network. Router fails to operate if lock_path is not set.
- [ ] This is a doc addition request.
- [ ] I have a fix to the document that I can paste below including example: input and output. 

Detail:
- Rocky clean install followinf the self-service network model
- While creating the sample networks and router the following issues arise when running throug the verifications
    1) ip netns <-- shows qdhcp namespaces but no qrouter
    2) openstack port list --router router <-- shows the interdaces in down states
After researching the log files i see in /var/log/neutron/neutron-l3-agent.log that the required parameter lock_path is missing

I've edited the /etc/neutron/neutron.conf and in the [oslo_concurrency] have set 
lock_path = /var/lib/neutron/tmp

After reinit:
- /var/log/neutron/neutron-l3-agent.log is clean, 
- ip netns shows 2 qdhcp and one qrouter as expected
- openstack port list --router router <- Ports are shown as active

Therefore my guess is that neutron install guide should be updated to
reflect this needed paramenter.

Thanks a lot in advance.
