	On Linux, scan /sys/class/net for devices if we have it; scan

	  errors, and check for the errors in question.
	Note that poll() works on BPF devices is Snow Leopard

	  gone away.  Deal with it.
	For BPF, raise the default capture buffer size to from 32k to 512k

	 can print better diagnostic information
	Return PCAP_ERROR_PERM_DENIED if we don't have permission to open a device, so
	 applications can tell the user they need to go play with permissions
	On Linux, ignore ENETDOWN so we can continue to capture packets if the 
	 interface goes down and comes back up again.

Tuesday January 9, 2001. guy@alum.mit.edu. Summary for 0.6 release

	New Linux libpcap implementation, which, in 2.2 and later
	kernels, uses PF_PACKET sockets and supports kernel packet
	filtering (if compiled into the kernel), and supports the "any"
	device for capturing on all interfaces.  Cleans up promiscuous
	mode better on pre-2.2 kernels, and has various other fixes
	(handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better,
	doesn't show duplicate packets on loopback interface, etc.).

	Fixed HP-UX libpcap implementation to correctly get the PPA for
	an interface, to allow interfaces to be opened by interface name.

	libpcap savefiles have system-independent link-layer type values
	in the header, rather than sometimes platform-dependent DLT_
	values, to make it easier to exchange capture files between
	different OSes.

	Non-standard capture files produced by some Linux tcpdumps, e.g.
	the one from Red Hat Linux 6.2 and later, can now be read.

	Updated autoconf stock files.

	Filter expressions can filter on VLAN IDs and various OSI
	protocols, and work on Token Ring (with non-source-routed
	packets).

	"pcap_open_dead()" added to allow compiling filter expressions
	to pcap code without opening a capture device or capture file.

	Header files fixed to allow use in C++ programs.

	Removed dependancy on native headers for packet layout.
	Removed Linux specific headers that were shipped.

	Security fixes: Strcpy replaced with strlcpy, sprintf replaced
	with snprintf.

	Fixed bug that could cause subsequent "pcap_compile()"s to fail
	erroneously after one compile failed.

	Assorted other bug fixes.

	README.aix and README.linux files added to describe
	platform-specific issues.

	"getifaddrs()" rather than SIOCGIFCONF used, if available.

itojun@iijlab.net
- Brought in KAME IPv6/IPsec bpf compiler.
- Fixes for NetBSD.

Assar Westerlund  <assar@sics.se>
- Building outside the source code tree fixed.
- Changed to write out time stamps with 32-bit seconds and microseconds
  fields, regardless of whether those fields are 32 bits or 64 bits in

- Changed "pcap_lookupdev()" to dynamically grow the buffer into which
  the list of interfaces is read as necessary in order to hold the
  entire list.

Greg Troxel <gdt@ir.bbn.com>
- Added a new "pcap_compile_nopcap()", which lets you compile a filter
  expression into a BPF program without having an open live capture or
  capture file.

- Added support for Fore ATM interfaces (qaa and fa) under IRIX. Thanks
  to John Hawkinson (jhawk@mit.edu)

- Fddi supports broadcast as reported by Jeff Macdonald
  (jeff@iacnet.com). Also correct ieee802 and arcnet.

  timeouts.

  for "lo" followed by an eos or digit (newer versions of Linux
  apparently call the loopback "lo" instead of "lo0").

  IRIX 5. Thanks to J. Eric Townsend (jet@abulafia.genmagic.com).

- Hack around deficiency in Ultrix's make.
