Two small problems with libpcap

Hi

I spotted two small problems with libpcap:

      * Preables for received PP frames are missing, the dedected.org
        tools used to include the preamble as well. This can easily be
        fixed by adding a default preamble if the kernel doesn't report
        the preamble to the userspace.
      * The slottime wraps around at 2^12 and not at 2^11 as it used to
        wrap around with the dedected.org tools. I am not sure about the
        best solution here, one could also use the full 16 bits for the
        time which are available in the header.
