    <#
    .SYNOPSIS
    This module performs strict parameter validation of advanced registry keys and switch validation for Azure Stack HCI devices.
 
    .DESCRIPTION
    Advanced registry keys are administrator controls for NIC properties. This module validates that those advanced properties
    follow the defined specification by Microsoft, validating that each key is of an appropriate type and accepts valid values.
 
    Additionally, this module performs validation of Azure Stack HCI switch requirements. These requirements are listed here:
    https://docs.microsoft.com/en-us/azure-stack/hci/concepts/physical-network-requirements
 
    This module is intended to be run through the automated Hardware Lab Kit (HLK) device tests for NICs or switches
 
    The following NIC tests are performed:
    - Tests the keys are the correct type (enum or int of 1-byte, 2-bytes, 3-bytes, or 4-bytes)
    - Tests the keys have the correct default values
    - Tests that enums contains all the right values
    - Tests that enums do not contain unauthorized values
    - Tests that ints have the correct Base
    - Tests that ints have the correct Max
    - Tests that ints have the correct Min
    - Tests that ints have the correct Step
    - Not Implemented Yet: Existance of required keys per documented requirements
 
    The following NicSwitch tests are performed
    - Tests the Name, Flags, SwitchType, SwitchId
    - Tests the min number of VFs
 
    The following NDIS tests are performed:
    - Tests that the minimum NDIS version is used for that OS and adapter

    .SYNOPSIS
    This module performs strict parameter validation of advanced registry keys and switch validation for Azure Stack HCI devices.
 
    .DESCRIPTION
    Advanced registry keys are administrator controls for NIC properties. This module validates that those advanced properties
    follow the defined specification by Microsoft, validating that each key is of an appropriate type and accepts valid values.
 
    Additionally, this module performs validation of Azure Stack HCI switch requirements. These requirements are listed here:
    https://docs.microsoft.com/en-us/azure-stack/hci/concepts/physical-network-requirements
 
    This module is intended to be run through the automated Hardware Lab Kit (HLK) device tests for NICs or switches
 
    The following Switch tests are performed:
    - Tests that 802.1AB packets are sent from the switch
    - Tests that 802.1 Subtype 1 is sent, only 1 valid VLAN is sent, and cannot be 0
    - Tests that 802.1 Subtype 3 is sent, contains only valid vlans, and supports at least 10 vlans.
    - Tests that 802.1 Subtype 11 is sent and has at least one priority enabled between priority 0 - 7
    - Tests that 802.3 Subtype 4 is sent and has at least an MTU of 9200 or higher
 
    Switch Setup Instructions:
    - Enable Native VLAN of non-zero value
    - Ensure at least 10 VLANs are trunked on the switchport
    - Enable Jumbo Frames of 9174
    - Enable PFC on at least 1 of priority0 - priority 7
    - Enable LLDP 802.1AB on the switchport and subtypes 802.1 Subtype 1, 3, 11 and 802.3 Subtype 4
