AFAIK there is no usage of memory mapped access into current libpcap tree. A kind of fork of libpcap, which use the mmap interface for packet socket, is maintained here: http://public.lanl.gov/cpw/ It use a writable mapping and in place header substitution. The mmap write access to the packet socket receive ring is 'safer' because the ring is composed by fixed length chunk (the user can't break the consistency of the received packet chain).
