Merge remote-tracking branch 'goog/tcpdump'
* goog/tcpdump: (1872 commits)
Remove old version. Getting ready for new libpcap 1.5
Remove commas from clauses in a comma-separated list.
Fix typo.
Describe all NFLOG TLV types and define structures for some of them.
Check caplen in the NFLOG TLV loop.
Have nflog_tlv_t include only the TLV header.
Byte-swap the T and L in TLVs as necessary when reading an NFLOG file.
Don't support D-Bus sniffing on OS X.
Add post-1.5.2 bug fixes.
Tag some changes with a bug identifier.
Add items for 1.5.1 and 1.5.2.
Formatting tweak.
Count *ring buffer blocks*, not *packets* to be filtered in userland.
Add a PACKET_COUNT_IS_UNLIMITED() to test for a packet count <= 0.
Use HAVE_TPACKET3 rather than TPACKET_V3 to test for TPACKET_V3 support.
Fix builds on systems without TPACKET_V3.
tweak manpages formatting
Fix pcap_loop() with a count of 0 and TPACKET_V3.
Discourage the use of a zero timeout.
We can't use TPACKET_V3 in immediate mode, so fall back on TPACKET_V2.

+.SH NAME
+pcap_lookupnet \- find the IPv4 network number and netmask for a device
+.SH SYNOPSIS
+.nf
+.ft B
+#include <pcap/pcap.h>
+.ft
+.LP
+.nf
+.ft B
+char errbuf[PCAP_ERRBUF_SIZE];
+.ft
+.LP
+.ft B

+.SH DESCRIPTION
+.B pcap_lookupnet()
+is used to determine the IPv4 network number and mask
+associated with the network device
+.IR device .
+Both
+.I netp
+and
+.I maskp
+are
+.I bpf_u_int32
+pointers.
+.SH RETURN VALUE
+.B pcap_lookupnet()
+returns 0 on success and \-1 on failure.
+If \-1 is returned,
+.I errbuf
+is filled in with an appropriate error message.
+.I errbuf
+is assumed to be able to hold at least
+.B PCAP_ERRBUF_SIZE
+chars.
