Subject: [PATCH] rt2x00: do not increment sequence number while
re-transmitting
Currently STA+AP re-transmitting the management frames with
incremented sequence number if hardware is assigning the sequence.
Fix is to assign the sequence number for Beacon by hardware
and for other Management frames software will assign the
sequence number

Subject: [PATCH] mac80211: add stop/start logic for software TXQs
Sometimes, it is required to stop the transmissions momentarily and
resume it later; stopping the txqs becomes very critical in scenarios where
the packet transmission has to be ceased completely. For example, during
the hardware restart, during off channel operations,
when initiating CSA(upon detecting a radar on the DFS channel), etc.
The TX queue stop/start logic in mac80211 works well in stopping the TX
when drivers make use of netdev queues, i.e, when Qdiscs in network layer
take care of traffic scheduling. Since the devices implementing
wake_tx_queue can run without Qdiscs, packets will be handed to mac80211
directly without queueing them in the netdev queues.
Also, mac80211 does not invoke any of the
netif_stop_*/netif_wake_* APIs if wake_tx_queue is implemented.
Since the queues are not stopped in this case, transmissions can continue
and this will impact negatively on the operation of the wireless device.
For example,
During hardware restart, we stop the netdev queues so that packets are
not sent to the driver. Since ath10k implements wake_tx_queue,
TX queues will not be stopped and packets might reach the hardware while
it is restarting; this can make hardware unresponsive and the only
possible option for recovery is to reboot the entire system.
There is another problem to this, it is observed that the packets
were sent on the DFS channel for a prolonged duration after radar
detection impacting the channel closing time.
We can still invoke netif stop/wake APIs when wake_tx_queue is implemented
but this could lead to packet drops in network layer; adding stop/start
logic for software TXQs in mac80211 instead makes more sense; the change
proposed adds the same in mac80211.

Subject: [PATCH] mac80211: do not call driver wake_tx_queue op during reconfig
There are several scenarios in which mac80211 can call drv_wake_tx_queue
after ieee80211_restart_hw has been called and has not yet completed.
Driver private structs are considered uninitialized until mac80211 has
uploaded the vifs, stations and keys again, so using private tx queue
data during that time is not safe.
The driver can also not rely on drv_reconfig_complete to figure out when
it is safe to accept drv_wake_tx_queue calls again, because it is only
called after all tx queues are woken again.
To fix this, bail out early in drv_wake_tx_queue if local->in_reconfig
is set.

Subject: [PATCH] mac80211: Add TXQ scheduling API
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This adds an API to mac80211 to handle scheduling of TXQs. The interface
between driver and mac80211 for TXQ handling is changed by adding two new
functions: ieee80211_next_txq(), which will return the next TXQ to schedule
in the current round-robin rotation, and ieee80211_return_txq(), which the
driver uses to indicate that it has finished scheduling a TXQ (which will
then be put back in the scheduling rotation if it isn't empty).
The driver must call ieee80211_txq_schedule_start() at the start of each
scheduling session, and ieee80211_txq_schedule_end() at the end. The API
then guarantees that the same TXQ is not returned twice in the same
session (so a driver can loop on ieee80211_next_txq() without worrying
about breaking the loop.
Usage of the new API is optional, so drivers can be ported one at a time.
In this patch, the actual scheduling performed by mac80211 is simple
round-robin, but a subsequent commit adds airtime fairness awareness to the
scheduler.

Subject: [PATCH] cfg80211: Add airtime statistics and settings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This adds TX airtime statistics to the cfg80211 station dump (to go along
with the RX info already present), and adds a new parameter to set the
airtime weight of each station. The latter allows userspace to implement
policies for different stations by varying their weights.

Subject: [PATCH] mac80211: Add airtime accounting and scheduling to TXQs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This adds airtime accounting and scheduling to the mac80211 TXQ
scheduler. A new callback, ieee80211_sta_register_airtime(), is added
that drivers can call to report airtime usage for stations.
When airtime information is present, mac80211 will schedule TXQs
(through ieee80211_next_txq()) in a way that enforces airtime fairness
between active stations. This scheduling works the same way as the ath9k
in-driver airtime fairness scheduling. If no airtime usage is reported
by the driver, the scheduler will default to round-robin scheduling.
For drivers that don't control TXQ scheduling in software, a new API
function, ieee80211_txq_may_transmit(), is added which the driver can use
to check if the TXQ is eligible for transmission, or should be throttled to
enforce fairness. Calls to this function must also be enclosed in
ieee80211_txq_schedule_{start,end}() calls to ensure proper locking.
The API ieee80211_txq_may_transmit() also ensures that TXQ list will be
aligned aginst driver's own round-robin scheduler list. i.e it rotates
the TXQ list till it makes the requested node becomes the first entry
in TXQ list. Thus both the TXQ list and driver's list are in sync.

Subject: [PATCH] mac80211: Expose ieee80211_schedule_txq() function
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Since we reworked ieee80211_return_txq() so it assumes that the caller
takes care of logging, we need another function that can be called without
holding any locks. Introduce ieee80211_schedule_txq() which serves this
purpose.

Subject: [PATCH] mac80211: add TX_NEEDS_ALIGNED4_SKBS hw flag
The driver should set this flag if the hardware requires tx skb data
(starting with the LLC header) to be aligned to 4 bytes.
Padding is added after ieee80211_hdr, before IV/LLC.
Before this patch, we have to do memmove(hdrlen) twice in the driver:
Once before we pass this to HW and once again in tx completion
(to fix up the skb for monitor mode).
With this patch we can skip this memmove() and thus reduce CPU cycles in
the data path.

Subject: [PATCH] mac80211: rework locking for txq scheduling / airtime
fairness
Holding the lock around the entire duration of tx scheduling can create
some nasty lock contention, especially when processing airtime information
from the tx status or the rx path.
Improve locking by only holding the active_txq_lock for lookups / scheduling
list modifications.

Subject: [PATCH] mac80211: set NETIF_F_LLTX when using intermediate tx
queues
When using iTXQ, tx sequence number allocation and statistics are run at
dequeue time. Because of that, it is safe to enable NETIF_F_LLTX, which
allows tx handlers to run on multiple CPUs in parallel.

Subject: [PATCH] mac80211: add NEED_ALIGNED4_SKBS hw flag
HW/driver should set NEED_ALIGNED4_SKBS flag in case
require aligned skbs to four-byte boundaries.
This affect only TX direction.
Padding is added after ieee80211_hdr, before IV/LLC.
Before we have to do memmove(hdrlen) twice in the
dirver. Once before we pass this to HW and next
in tx completion (to be sure monitor will report
this tx frame correctly).
With this patch we can skip this memmove() and save CPU.
Currently this was tested with ath9k, both hw/sw crypt for
wep/tkip/ccmp.
