wifi: mac80211: Drop support for TX push path

2022-10-10T09:06:14Z

All drivers are now using mac80211 internal queues (iTXQs). Drop mac80211 internal support for the old push path. Signed-off-by: Alexander Wetzel Signed-off-by: Johannes Berg

mac80211: when using iTXQ, select the queue in ieee80211_subif_start_xmit

2019-04-26T11:02:11Z

When using iTXQ, the network stack does not need the real queue number, since mac80211 is using its internal queues anyway. In that case we can defer selecting the queue and remove a redundant station lookup in the tx path to save some CPU cycles. Signed-off-by: Felix Fietkau Signed-off-by: Johannes Berg

mac80211: add WMM admission control support

2014-10-22T08:42:09Z

Use the currently existing APIs between mac80211 and the low level driver to implement WMM admission control. The low level driver needs to report the media time used by each transmitted packet in ieee80211_tx_status. Based on that information, mac80211 will modify the QoS parameters of the admission controlled Access Category when the limit is reached. Once the original QoS parameters can be restored, mac80211 will do so. One issue with this approach is that management frames will also erroneously be downgraded, but the upside is that the implementation is simple. In the future, it can be extended to driver- or device-based implementations that are better. Signed-off-by: Emmanuel Grumbach Signed-off-by: Johannes Berg

mac80211: save wmm_acm per sdata

2012-06-20T15:35:22Z

Save and configure the wmm_acm per sdata, rather than per hardware. If wmm_acm is saved per hardware when running two interfaces simultaneously on the same hardware one interface's wmm policy will be affected by the other interface.

mac80211: fix forwarded mesh frame queue mapping

2011-11-28T19:44:05Z

We can't rely on ieee80211_select_queue() to do its job at this point since the skb->protocol is not yet known. Instead, factor out and reuse the queue mapping logic for injected frames. Also, to mitigate congestion, forwarded frames should be dropped if the outgoing queue was stopped. This was not correctly implemented as we were not checking the right queue. Furthermore, we were dropping frames that had arrived to their destination if that queue was stopped. Signed-off-by: Thomas Pedersen Signed-off-by: Javier Cardona Signed-off-by: John W. Linville

mac80211: Mesh data frames must have the QoS header

2011-09-14T17:56:50Z

Per sec 7.1.3.5 of draft 12.0 of 802.11s, mesh frames indicate the presence of the mesh control header in their QoS header. Signed-off-by: Javier Cardona Signed-off-by: John W. Linville

wireless: unify QoS control field definitions

2011-06-27T19:09:39Z

Move all that mac80211 has into the generic ieee80211.h header file and use them. At the same time move them from mask+shift to just bits and rename them for consistent names. Signed-off-by: Johannes Berg Signed-off-by: John W. Linville

mac80211: fix skb buffering issue

2010-01-05T21:21:40Z

Since I removed the master netdev, we've been keeping internal queues only, and even before that we never told the networking stack above the virtual interfaces about congestion. This means that packets are queued in mac80211 and the upper layers never know, possibly leading to memory exhaustion and other problems. This patch makes all interfaces multiqueue and uses ndo_select_queue to put the packets into queues per AC. Additionally, when the driver stops a queue, we now stop all corresponding queues for the virtual interfaces as well. The injection case will use VO by default for non-data frames, and BE for data frames, but downgrade any data frames according to ACM. It needs to be fleshed out in the future to allow chosing the queue/AC in radiotap. Reported-by: Lennert Buytenhek Signed-off-by: Johannes Berg Cc: stable@kernel.org [2.6.32] Signed-off-by: John W.
