config:
description:
- The module, by default, will connect to the remote device and
retrieve the current running-config to use as a base for comparing
against the contents of source. There are times when it is not
desirable to have the task get the current running-config for
every task in a playbook. The I(config) argument allows the
implementer to pass in the configuration to use as the base
config for comparison.

description:
- The C(state) argument controls the operational state of eAPI
on the remote device. When this argument is set to C(started),
