short_description: Collect facts from remote devices running MikroTik RouterOS
description:
  - Collects a base set of device facts from a remote device that
    is running RotuerOS.  This module prepends all of the
    base network fact keys with C(ansible_net_<fact>).  The facts
    module will always collect a base set of facts from the device
    and can enable or disable collection of additional facts.
options:
  gather_subset:
    description:
      - When supplied, this argument will restrict the facts collected
        to a given subset.  Possible values for this argument include
        C(all), C(hardware), C(config), and C(interfaces).  Can specify a list of
        values to include a larger subset.  Values can also be used
        with an initial C(!) to specify that a specific subset should
        not be collected.
    required: false
    default: '!config'
