The FreeBSD networking stack has been the 'default' infrastructure networking for Microsoft for many years. Think about it, while SMB is Windows only, TCP/IP, NFS, and other networking protocols and technologies are "Internet" (built on UNIX) technologies which rule the world.
Many Microsoft supporters in USA and elsewhere 'refused' to accept this fact - even as confirmed by Microsoft itself, and only accept pure Microsoft only innovative (yuk) and developed technology, even as such MS technology is broken and/or does not work at all.
Such is the mentality of Microsoft dupes, gladly eating pure MS crap.
