    kernel - Force NFSv3 for diskless nfs mount
    
    * Ignore any file handles passed from bootp.  These are NFSv2 handles
      and NFSv2 just doesn't have the directory support needed if the
      server is running a filesystem with 64-bit directory cookies (as HAMMER
      does).
    
      This will force the kernel's diskless nfs mount to re-authorize and
      acquire a NFSv3 handle for the root mount.
    
    * Undo a bit of a previous commit where I tried to enable readdirplus for
      NFSv2 to workaround NFSv2 directory cookie issues.  It just doesn't work.
      readdirplus is again force-disabled for NFSv2 mounts.
