description:
Put the BPF DLT_* constants into their own header file so that things
that reference them don't have to slurp in all of the BPF headers.

Define a new generic RAWAF type that is like DLT_RAW, but isn't specific
to IP (the macro takes an AF_* constant as an argument to generate the
actual type).
