Source       : libssh-0.9.6-1.fc35.src.rpm

OS / ENVIRONMENT

STEPS TO REPRODUCE

ansbile.cfg 
--------------
[persistent_connection]
ssh_type = libssh

inventory
------------
[iosDevice1]
localhost

[iosDevice1:vars]
ansible_network_os=ios
ansible_user=user
ansible_password=pass
ansible_connection=network_cli
ansible_network_cli_ssh_type=libssh
ansible_become=true
ansible_ssh_port=8022

playbook.yml
--------------
---
- name: Tests libssh
  hosts: iosDevice1
  gather_facts: no
  tasks:
  - name: Gathering vlans
    cisco.ios.ios_facts:
      gather_subset: ['!all', '!min']
      gather_network_resources: ['vlans']

EXPECTED RESULTS

Works properly with connection paramiko, same should be with libssh
