Are you asking me a Windows question, hahahaha. I have no idea how the Windows driver use that value. All I know is that
 there is only 3 settings default/4096/9016 (not sure about the 4096, don't have access to that PC at the moment).

Our switch support 16K frame though, which are neither available in QNX and Windows.
