b3c43c3c24 wlantest: Allow duplicate frame processing after decryption failure
If a sniffer capture does not include FCS for each frame, but may
included frames with invalid FCS, it would be possible for wlantest to
try to decrypt the first received frame and fail (e.g., due to CCMP MIC
mismatch) because that particular frame was corrupted and then ignore
the following retry of that frame as a duplicate even if that retry has
different payload (e.g., if its reception did not show corruption).

Work around this by skipping duplicate frame detection immediately
following a decryption failure.

e2991ee580 Move CRC-32 routine from wlantest to src/utils
This allows the CRC-32 routine to be shared for other purposes in
addition to the WEP/TKIP/FCS within wlantest.

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.

e4d99217f7 wlantest: Use add_note() to annotate frames
This adds debug information from wlantest into pcapng frame comments to
make the information more convenient to use, e.g., in Wireshark.

2531517600 wlantest: Add -F option for assuming FCS is included
When using DLT_IEEE802_11 datalink type in a pcap file, wlantest can now
be instructed to assume there is an FCS included in the frame by adding
the new -F command line argument. This will make wlantest validate the
FCS and strip it from the frame before processing.

44f6d554ee wlantest: Process TX status frames as RX frames too
This is needed to allow capture files from the mac80211 cooked monitor
mode interface to be processed properly. Without this, the locally
generated frames may not get processed.

This tool can be used to capture IEEE 802.11 frames either from a

offline analysis. This version is only adding basic infrastructure for
going through the frames and parsing their headers.
