<#
.SYNOPSIS
    Get all information about interfaces on your local machine

.DESCRIPTION
    Particularly useful for Core
    Will not work with Core less than 7.x on WSL; only Core greater than 7.x currently works in WSL

.PARAMETER AddressFamily
    This parameter is OPTIONAL
    This parameter takes a string that has a value of either "IPv4" or "IPv6"

.PARAMETER OperationalStatus
    This parameter is OPTIONAL
    This parameter takes a string that has a value of either "UP" or "DOWN"
    OperationalStatus values are not returned in WSL

.EXAMPLE
    # On Windows
    PS C:\Users\testadmin> Get-NetworkInfo -AddressFamily "IPv4" OperationalStatus "UP"

.EXAMPLE
    # On Linux
    PS /home/pdadmin/Downloads> Get-NetworkInfo -AddressFamily "IPv4" -OperationalStatus "DOWN"
