Right. At first the copy was only for the case where the skbuff was
too small, then I had to copy it every time because of the TCP
retransmit issue (and I want to revert it if possible :-).
My encryption routines work in-place, because I wanted the copy to be
the exception not the rule. I probably should set up some
statistics...
