they are nicer as enums, so rewrite the file from the

Use the existing device timestamp from the RX status information
to add support for the new radiotap timestamp field. Currently
only 32-bit counters are supported, but we also add the radiotap
mactime where applicable. This new field allows more flexibility
in where the timestamp is taken etc. The non-timestamp data in
the field is taken from a new field in the hw struct.

This capabilities weren't propagated to the radiotap header.
We don't set here the VHT_KNOWN / MCS_HAVE flag because not
all the low level drivers will know how to properly flag
the frames, hence the low level driver will be in charge
of setting IEEE80211_RADIOTAP_MCS_HAVE_FEC,
IEEE80211_RADIOTAP_MCS_HAVE_STBC and / or
IEEE80211_RADIOTAP_VHT_KNOWN_STBC according to its
capabilities.

Wireshark already defines radiotap channel flags for 5 and 10 MHz, so
just use them in Linux radiotap too. Furthermore, add rx status flags to
allow drivers to report when they received data on 5 or 10 MHz channels.

Some chips can tell us if received frame was
encoded with STBC or not. To make this information available
in user space we can use updated radiotap specification:
http://www.radiotap.org/defined-fields/MCS

This patch will set number of STBC encoded spatial streams (Nss).
The HAVE_STBC flag should be provided by driver.

Upstream radiotap has adopted the namespace
proposal David Young made and I then took care
of, for which I had adapted the radiotap parser
as a library outside the kernel. This brings
the in-kernel parser up to speed.

      mac80211: make rx radiotap header more flexible

code was added that tried to align the radiotap header
position in memory based on the radiotap header length.
Quite obviously, that is completely useless.

Instead of trying to do that, use unaligned accesses
to generate the radiotap header. To properly do that,
we also need to mark struct ieee80211_radiotap_header
packed, but that is fine since it's already packed
(and it should be marked packed anyway since its a
wire format).

Radiotap was updated to include a "bad PLCP" flag and standardise
the "bad FCS" flag in the "flags" rather than "RX flags" field,
this patch updates Linux to that standard.
