module: fortios_system_tos_based_priority
short_description: Configure Type of Service (ToS) based priority table to set network traffic priorities in Fortinet's FortiOS and FortiGate.
description:
    - This module is able to configure a FortiGate or FortiOS (FOS) device by allowing the
      user to set and modify system feature and tos_based_priority category.
      Examples include all parameters and values need to be adjusted to datasources before usage.
      Tested with FOS v6.0.5
version_added: "2.9"
author:
    - Miguel Angel Munoz (@mamunozgonzalez)
    - Nicolas Thomas (@thomnico)
notes:
    - Requires fortiosapi library developed by Fortinet
    - Run as a local_action in your playbook
requirements:
    - fortiosapi>=0.9.8
