2019-08-11radiotap: Comment that there are no more header bit numbers left.Richard Sharpe1-5/+13
The new approach for radiotap headers is TLVs. Let people know there are no more bits available for headers and point them to the correct place: www.radiotap.org.

2018-09-10radiotap: Correct support for 0-length PSDUs.Richard Sharpe1-1/+1
When there is no data, which is indicated by the 0-length PDSU radiotap header, there is no more data to dissect, so don't dissect any more as that causes an exception.

Johannes made changes in the handling of LTF Symbols and LTF Symbol count which are sort of backward compatible. This brings us into conformance with those.

If a field is indicated as not known, then display that field as reserved which will prevent people from searching for fields that are not known and makes more sense. Also, rename some of the hf fields to be more in line with standard practice.

2015-06-22Provide PHY type and band information in the 802.11 pseudo-header.Guy Harris1-8/+30
Provide that information so that the "802.11 radio information" protocol can indicate whether a packet was 802.11 legacy/11b/11a/11g/11n/11ac, and possibly whether it's 2.4 GHz or 5 GHz 11n. (Sometimes the center frequency might not be supplied, so the band information can be useful.) Also, provide some 11ac information, now that we can distinguish between 11n and 11ac. Don't calculate the data rate from the MCS index unless it's 11n; we don't yet have code to calculate it for 11ac. For radiotap, only provide guard interval information for 11n and 11ac, not for earlier standards. Handle the 11ac flag in the Peek remote protocol. For Peek tagged files, the "extension flags" are 11n/11ac flags, so we don't have to check for the "MCS used" bit in order to decide that the packet is 11n or 11ac or to decide whether to provide the "bandwidth" or "short GI" information.
