Simon Wunderlich a5e70697d0 mac80211: add radiotap flag and handling for 5/10 MHz
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.

Oleksij Rempel 786677d100 mac80211: add STBC flag for radiotap
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.

This at least lets one see the MCS and NSS information.

Johannes Berg 776d68f863 wireless: move ieee80211chan2mhz macro
The macro is only used in ipw2200 and we certainly
don't want to encourage its use, so move it out of
the radiotap header file and into the driver.

Johannes Berg 33e5a2f776 wireless: update radiotap parser
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).

Johannes Berg aae89831df wireless: radiotap updates
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.

No need to pad the header so no constant needed for that,
no need to carry any version number from netbsd nor CVS
