2011-09-13mac80211: Remove unnecessary OOM logging messagesJoe Perches
Removing unnecessary messages saves code and text. Site specific OOM messages are duplications of a generic MM out of memory message and aren't really useful, so just delete them. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-12-21mac80211: reduce reliance on netdevJohannes Berg
For bluetooth 3, we will most likely not have a netdev for a virtual interface (sdata), so prepare for that by reducing the reliance on having a netdev. This patch moves the name and address fields into the sdata struct and uses them from there all over. Some work is needed to keep them sync'ed, but that's not a lot of work and in slow paths anyway. In doing so, this also reduces the number of pointer dereferences in many places, because of things like sdata->dev->dev_addr becoming sdata->vif.addr.

2009-11-18mac80211: remove encrypt parameter from ieee80211_tx_skbJohannes Berg
Since the flags moved into skb->cb, there's no longer a need to have the encrypt bool passed into the function, anyone who requires it set to 0 (false) can just set the flag directly. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-05-20mac80211: move channel switch codeJohannes Berg
The channel switch code is currently in the spectrum management file, where arguably it belongs. However, it is for managed mode only and uses the structures for that mode only so having it in a more generic file can be confusing. Additionally, my next patch gets simpler with the code here. When/if we ever implement this for IBSS or mesh then we will need to rework the structures it uses anyway at which point we could move the code back.

2009-04-22cfg80211: clean up includesJohannes Berg
Trying to separate header files into net/wireless.h and net/cfg80211.h has been a source of confusion. Remove net/wireless.h (because there also is the linux/wireless.h) and subsume everything into net/cfg80211.h -- except the definitions for regulatory structures which get moved to a new header net/regulatory.h. The "new" net/cfg80211.h is now divided into sections. There are no real changes in this patch but code shuffling and some very minor documentation fixes. I have also, to make things reflect reality, put in a copyright line for Luis to net/regulatory.h since that is probably exclusively written by him but was formerly in a file that only had my copyright line.

2009-02-27mac80211: split IBSS/managed codeJohannes Berg
This patch splits out the ibss code and data from managed (station) mode. The reason to do this is to better separate the state machines, and have the code be contained better so it gets easier to determine what exactly a given change will affect, that in turn makes it easier to understand. This is quite some churn, especially because I split sdata->u.sta into sdata->u.mgd and sdata->u.ibss, but I think it's easier to maintain that way. I've also shuffled around some code -- null function sending is only applicable to managed interfaces so put that into that file, some other functions are needed from various places so put them into util, and also rearranged the prototypes in ieee80211_i.h accordingly.

2009-02-13mac80211: use cfg80211s BSS infrastructureJohannes Berg

2009-01-29mac80211: Handle power constraint level advertised in 11d+h beaconVasanthakumar Thiagarajan
This patch uses power constraint level while determining the maximum transmit power, there by it makes sure that any power mitigation requirement for the channel in the current regulatory domain is met.

2009-01-29mac80211: 802.11w - Do not force Action frames to disable encryptionJouni Malinen
When sending out Action frames, allow ieee80211_tx_skb() to send them without enforcing do_not_encrypt. These frames will be encrypted if MFP has been negotiated.

2008-09-11mac80211: move frame TX functionJohannes Berg
The ieee80211_sta_tx function isn't MLME code any more, it's getting used by a lot of code. Move it to utils and rename it to ieee80211_tx_skb. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-09-11mac80211: move spectrum management code outJohannes Berg
Like the HT code, this doesn't depend on the STA-mode implementation and can be handled entirely independently. There's only stub code for now, but when it gets filled having it in its own file will be beneficial. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
