This was the original mount behaviour. This was recently changed to
mount -t fstype <ip> /dir, mainly to allow making the fstype option
optional for autodetecting the type. The wiki page is out of date here.
As a sidenote I brought back the old behaviour as a compatibility option
to not break old environments.

mount -t tftp /mnt/tftp

The special thing about tftp is that tftp does not have directory
listing support, so you will always see an empty directory, even when
mounted. The files are there nevertheless and can be accessed.
