handle" routine, an 'activate a pcap_t handle" routine, and some "set
the properties of the pcap_t handle" routines, so that, for example, the
buffer size can be set on a BPF device before the device is bound to an
interface.
Add additional routines to set monitor mode, and make at least an
initial attempt at supporting that on Linux, *BSD, and Mac OS X 10.4 and
10.5.
Have a "timeout" member of the pcap_md structure on all platforms, use
that on Windows instead of the "timeout" member of the pcap_t structure,
and get rid of the "timeout" member of that structure.
move it into pcap-sita.c, and make --with-sita set the pcap type to
"sita", so we build pcap-sita.c instead of, rather than in addition to,
pcap-linux.c.
Use "bpf_u_int32" rather than "ulong" in the SITA code, as it's intended
to be 32 bits long (the "l" in "htonl()" and "ntohl()" is historical -
they work on 32-bit quantities, and the "l" dates back to the days when
32-bit processors were a bit newer and 16-bit Unix was more common).
Those changes also, at least in theory, makes the SITA support work on
other Unix-compatible platforms; note that in README.sita.
Clean up pcap-sita.c, making routines no longer called outside it
static, folding trivial wrappers, and fixing various warnings.
Put the routines used by fad-sita.c and defined by pcap-sita.c into
pcap-sita.h. Remove from pcap-sita.h the files that are now static to
pcap-sita.c. Include pcap-sita.h in both fad-sita.c and pcap-sita.c, so
that we do cross-file prototype checking.
if it does, use that for the pf definitions;
if it doesn't, don't compile in pf support;
as both OpenBSD and FreeBSD have changed the pf definitions and header
format without changing the DLT value, so you can't reliably read
pflog-format libpcap files on a machine running an OS version other than
the one on which the file was generated.

-const pcap_strerror() for consistency
gencode.c:
date: 2006/04/26 09:24:33; author: tron; state: Exp;
Add missing "const" keywords to match declarations in "pcap.h".
date: 2006/10/15 19:27:21; author: christos; state: Exp;
add a volatile variable to prevent vfork/longjmp clobbering.
optimize.c:
date: 2006/05/17 17:48:36; author: drochner; state: Exp;
Make the optimizer use unsigned numbers as the kernel does.
While it is not agreed on that purely unsigned arithmetics is nice,
different behaviour of optimized and unoptimized code is less desirable.
pcap-bpf.c:
date: 2006/02/27 15:51:38; author: drochner; state: Exp;
pull in from NetBSD's libpcap: use cloning bpf device on NetBSD
Have the configure script check for paths.h, so that we can include it
only if we have it, and use the cloning BPF device only if we're on
NetBSD *and* _PATH_BPF is defined (hopefully this will keep us from
using it on versions of NetBSD that don't have a cloning BPF device; if,
in the future, other OSes with BPF get cloning BPF devices, we can make
this work for them as well).
Linux. The USB sniffing code for Linux now supplies a per-packet header
based on the one supplied by the Linux binary sniffing interface, so we
add a new DLT_ value and use that.
Fix his e-mail address, and add him to the credits.
when building a shared library, build with "-fPIC" on Linux, to
support x86_64;
link with "$(CC) -shared" rather than "ld -shared" when building
a ".so" shared library (as would be done with ELF systems that
use GCC);
add an explicit "-ldag" when building the shared library, so the
DAG library dependency is explicit.
If the DAG API supports asking a card for the set of ERF types
it supports, use that capability, to handle cards that support
multiple ERF types. This is to support channelised/fractional
T1/E1.
Don't set the snapshot length - some DAG cards support multiple
capture streams, but the snapshot length is global, so it'd
affect other captures.
Update README.dag.
whether it succeeds or fails, so you can't erase a "no" result and try
again with a different header. Use AC_CHECK_DECL, which doesn't define
HAVE_DECL_xxx, and then explicitly define it based on whether we found a
declaration or not.
<netinet/ether.h> declares ether_hostton(), so the failure to find it
declared in <netinet/in_ether.h> doesn't cause us to assume we won't
find it anywhere.

make the second one similar.
Get rid of the # in the "Rechecking with some additional #includes"

<netinet/if_ether.h>, so we try the second test with the additional

Log a message before doing the second test, to show why we're testing

on Solaris, it's a "gethostbyname() -ish function", and we'll find it
only when we're linking with whatever libraries are required for finding
those functions.
Get the AC_LBL_LIBRARY_NET macro from tcpdump; that macro works with
autoconf 2.5x, but the one here didn't.
and if including it declares ether_hostton(), and define
HAVE_DECL_ETHER_HOSTTON appropriately, and use that to determine whether
to define it ourselves, rather than having a set of OSes that don't need
it, as that set can change over time.
Make the default declaration of "ether_hostton()" declare its first
argument as "const char *", as that's what it's *supposed* to be
(although it's not declared as such in some OSes, so we still have to
cast a "const char *" when passed as the first argument).
UN*Xy-enough platform that the Makefile.in rules to generate "version.h"
work), and use the stuff from "version.h" iff HAVE_VERSION_H is defined,
so we can use it even with WinPcap.
supplying a non-stub version of "pcap_findalldevs()", as a list of
devices won't do any good for a capture program.
Don't bother checking for "ifaddrs.h" unless we have "getifaddrs()" -
and if we have "getifaddrs()" but don't have a usable "ifaddrs.h",
report an error, rather than leaving the error for the compile stage.
"snprintf()", include one in libpcap with the name "pcap_snprintf()", so
applications don't have to supply their own "snprintf()" on those
platforms in order to use libpcap.
