420989085d wlantest: Ethernet interface capture
Allow option (command line argument -e) to capture Ethernet headers
instead of IEEE 802.11 so that wlantest can be used as a replacement for
tcpdump/dumpcap for capturing.

e929eb39d6 wlantest: Add -N command line argument to remove write buffering
This makes it easier to do live parsing of captured pcap files from
wlantest without having to rename and restart the capture file. Packet
writes are flushed to disk after each packet if -N is included in the
command line.

30476e4fe7 wlantest: Tag and ignore generated packets
Rather than ignoring packets with a minimal 8-byte radiotap
header, which may occur elsewhere, tag generated (decrypted)
packets with an empty vendor namespace tag and ignore those.

de36e348f9 wlantest: Always write radiotap pcap-ng
When writing pcap-ng files, always include a radiotap
header even if there wasn't one in the input. For now
just drop prism headers, I don't have any to test.

ba2beacc97 wlantest: Add support for writing pcapng files
The new -n<file> command line argument can be used to request wlantest
to write all read or captured frames into a pcapng file. This is similar
to the -w argument, but with pcapng allowing per-frame comments to be
embedded in the file.

ef00c78097 wlantest: Replace pcap header directory
The use of the pcap subdirectory seems to be limited to some of the
newer Linux distros only, so use the older paths to pcap.h and
pcap-bpf.h to make wlantest bit more easier to compile on older
systems.

64f45d070b wlantest: Add option for writing a PCAP dump file
The output file includes all the capture (or read from wireless PCAP
file) frames in their original contents and another copy of each
frame that is decrypted in wlantest (including EAPOL-Key Key Data
field).
