Patch for net-mgmt/p0f

[Clayton Milos]

Hi guys

I found that p0f doesn't work with the pflog interface. A bit of searching
and this patch turned up:
http://desync.com/~bw/patch-p0f.c

With it applied instead of the default patch it works. It looks like the
default patch has a few wrong line numbers in it and is missing the first
part of the patch.
Please could somebody commit the new patch.

Regards
Clay
