And yes, the kernel computes the hash. I agree, but since we a are trying to define a standard, we probably want to define a default hashing method. The main reason is that I don't think we'll be able to include in libpcap (and possibly the capture drivers) the support for 6 or 7 different methods, so maybe we could choose one.
