.SYNOPSIS
    Checks availability, state and Usage of Network interfaces and Interface Teams
.DESCRIPTION
    This plugin checks availability, status and load of a network adapter. It is also
    equipped with various parameters, so you have the possibility to decide almost
    everything by yourself, when the single checks have to be Warning or Critical. For the
    Team-Members Physical adapters no Performance Counter are displayed.
.ROLE

.PARAMETER NoPerfData

.PARAMETER Verbosity
    Changes the behavior of the plugin output which check states are printed:
    0 (default): Only service checks/packages with state not OK will be printed
    1: Only services with not OK will be printed including OK checks of affected check packages including Package config
    2: Everything will be printed regardless of the check state
    3: Identical to Verbose 2, but prints in addition the check package configuration e.g (All must be [OK])
