Yeah,. the TCP sequence number md5_transform() cases are likely the
best example of something where siphash might be good. That tends to
be really just a couple words of data (the address and port info) plus
the net_secret[] hash. I think they currently simply just fill in the
fixed-sized 64-byte md5-round area.

I wonder it's worth it to have a special spihash version that does
that same "fixed 64-byte area" thing.

But please talk to the netwotrking people. Maybe that's the proper way
to get this merged?
