86f82ef946 Add netmap support to libpcap. Tcpdump and other native pcap application can now
run directly on netmap ports using netmap:foo or valeXX:YY device names.
Modifications to existing code are small and trivial, the netmap-specific
code is all in a new file.

Please be aware that in netmap mode the physical interface is disconnected from
the host stack, so libpcap will steal the traffic not just make a copy.

For the full version of the code (including linux and autotools support) see
	https://code.google.com/p/netmap-libpcap/

5945b5f5ab Rename definition of IEEE80211_FC1_WEP to IEEE80211_FC1_PROTECTED.
The origin of WEP comes from IEEE Std 802.11-1997 where it defines
whether the frame body of MAC frame has been encrypted using WEP
algorithm or not.
IEEE Std. 802.11-2007 changes WEP to Protected Frame, indicates
whether the frame is protected by a cryptographic encapsulation
algorithm.

75bf2db380 Move new pf includes to the pf directory. The pfvar.h remain
in net, to avoid compatibility breakage for no sake.

The future plan is to split most of non-kernel parts of
pfvar.h into pf.h, and then make pfvar.h a kernel only
include breaking compatibility.

9dae57e134 Start splitting pfvar.h into internal and external parts.
- Provide pf_altq.h that has only stuff needed for ALTQ.
- Start pf.h, that would have all constant values and
  eventually non-kernel structures.
- Build ALTQ w/o pfvar.h, include if_var.h, that before
  came via pollution.
- Build tcpdump w/o pfvar.h.

c62908a982 Incorporate vendor commit ecdc5c0a7f7591a7cd4a:
In userland, sign extend the offset for JA instructions.

We currently use that to implement "ip6 protochain", and "pc" might be
wider than "pc->k", in which case we need to arrange that "pc->k" be
sign-extended, by casting it to bpf_int32.

e375b20400 Explicitly initialize the packet buffer to NULL after we unmap the zero copy
buffers.  This fixes a segfault on exit due to calling free on a bogus pointer.
This should be considered a temporary stop gap fix to avoid the crash.  The
complete fix re-shuffles the initializations of some of the clean-up pointers.

The details of the fix can be found in the libpcap git repository:

154bbe416c Implement zero-copy bpf(4) buffer or "zbuf" support for libpcap. A slightly
different version has been committed upstream in the libpcap vendor branch.
This will allow people to experiment with zero-copy bpf(4) without requiring
external patches.

Note to enable this functionality:

    sysctl net.bpf.zerocopy_enable=1

By default, libpcap will use the legacy buffering method unless this sysctl
variable is set to 1.

For the details about zero-copy bpf(4) implementation see svn change r177548.
