Using that argument, is that clearance to put all of the normalization
from pf into the various parts of the networking code (not every type of
normalisation needs to be done on every packet but it is all useful), with
sysctls to turn it on or off, and maybe we'll add the ability to log packets
at various points because we don't want the overhead of BPF (it has to
process every packet too) and that's just for starters. I'm sure I can
think of some more, in time. How about you?
If there were a core@ for freebsd that was active, this is the kind of
thing I'd be writing to them about, asking for it to be backed out.
