From Koryn Grant <[email protected]> - DAG support enhancements and fixes:

	Added support for nonblocking operation.

	Added support for processing more than a single packet in
	pcap_dispatch().

	Fixed bug in loss counter code.

	Improved portability of loss counter code (e.g. use UINT_MAX
	instead of 0xffff).

	Removed unused local variables.

	Added required headers (ctype.h, limits.h, unistd.h,
	netinet/in.h).

	Changed semantics to match those of standard pcap on linux.
		- packets rejected by the filter are not counted.
