TLS stands for Transport Layer Security so by definition, it is for the
transport layer. There's is nothing that prevents encryption at any
level. I don't see any problem with encrypting the frame at the link
layer, but that creates a lot of overhead. About the only advantage I
see is to avoid some man-in-the-middle attacks or to hide ip addresses
or other data in the tcp or ip headers.
