mac80211: propagate STBC / LDPC flags to radiotap

2014-02-06T08:34:58Z

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.

mac80211: add radiotap flag and handling for 5/10 MHz

2013-07-16T06:58:05Z

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.

mac80211: add STBC flag for radiotap

2013-05-24T10:07:25Z

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. Signed-off-by: Oleksij Rempel Signed-off-by: Johannes Berg

mac80211: support (partial) VHT radiotap information

2012-11-27T10:56:18Z

Add some information that we have about VHT to radiotap. This at least lets one see the MCS and NSS information. Signed-off-by: Johannes Berg

wireless: add radiotap A-MPDU status field

2012-08-20T11:53:09Z

Define the A-MPDU status field in radiotap, also update the radiotap parser for it and the MCS field that was apparently missed last time. Signed-off-by: Johannes Berg

wireless: move ieee80211chan2mhz macro

2011-11-11T17:32:50Z

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. Signed-off-by: Johannes Berg Signed-off-by: John W. Linville

mac80211: Allow noack flag overwrite for injected frames

2011-10-03T19:19:17Z

Allow injected unicast frames to be sent without having to wait for an ACK. Signed-off-by: Helmut Schaa Signed-off-by: John W. Linville

mac80211: add MCS information to radiotap

2011-01-28T20:44:29Z

This adds the MCS information we currently get from the drivers into radiotap. Signed-off-by: Johannes Berg Signed-off-by: John W. Linville

wireless: update radiotap parser

2010-02-08T21:50:53Z

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. Signed-off-by: Johannes Berg Signed-off-by: John W. Linville

mac80211: fix radiotap header generation

2009-10-30T20:49:20Z

In commit 601ae7f25aea58f208a7f640f6174aac0652403a Author: Bruno Randolf Date: Thu May 8 19:22:43 2008 +0200 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).
