/*
* This is libpcap's cut-down version of bpf.h; it includes only
* the stuff needed for the code generator and the userland BPF
* interpreter, and the libpcap APIs for setting filters, etc..
*
* "pcap-bpf.c" will include the native OS version, as it deals with
* the OS's BPF implementation.
*
* At least two programs found by Google Code Search explicitly includes
* <pcap/bpf.h> (even though <pcap.h>/<pcap/pcap.h> includes it for you),
* so moving that stuff to <pcap/pcap.h> would break the build for some
* programs.
*/
/*
* If we've already included <net/bpf.h>, don't re-define this stuff.
* We assume BSD-style multiple-include protection in <net/bpf.h>,
* which is true of all but the oldest versions of FreeBSD and NetBSD,
* or Tru64 UNIX-style multiple-include protection (or, at least,
* Tru64 UNIX 5.x-style; I don't have earlier versions available to check),
* or AIX-style multiple-include protection (or, at least, AIX 5.x-style;
* I don't have earlier versions available to check), or QNX-style
* multiple-include protection (as per GitHub pull request #394).
*
* We do not check for BPF_MAJOR_VERSION, as that's defined by
* <linux/filter.h>, which is directly or indirectly included in some
* programs that also include pcap.h, and <linux/filter.h> doesn't
* define stuff we need.
*
* This also provides our own multiple-include protection.
