Checkmk Werk 13348: <tt>windows_if.ps1</tt>: Use <tt>Get-NetAdapter</tt> if possible

ID: 13348 Title: <tt>windows_if.ps1</tt>: Use <tt>Get-NetAdapter</tt> if possible Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0i1 The Windows agent plugin <tt>windows_if.ps1</tt>, deployed via the bakery ruleset 'Network interfaces on Windows', collects additional data about network interfaces, such as aliasses and MAC addresses. Up to now, the plugin used <tt>Get-WmiObject Win32_NetworkAdapter</tt> to collect this information. However, <tt>Win32_NetworkAdapter</tt> is deprecated and might return wrong aliasses for certain network adapters. Now, the plugin attempts to use <tt>Get-NetAdapter</tt> instead. If this is not available, it falls back to <tt>Win32_NetworkAdapter</tt>. For most interfaces, this change should be compatible, since <tt>Win32_NetworkAdapter</tt> and <tt>Get-NetAdapter</tt> produce mostly identical output. However, as mentioned earlier, there might be interfaces for which e.g. the alias changes.
