ath10k/ath10k-ct: support multicast and management rate control
Drivers with software rate control can directly use the selected multicast rate for multicast/broadcast frames and the minimal basic rate for management frames. But drivers with offloaded rate control algorithms must be informed about such upper layer decisions to configure the hardware/firmware. A new BSS_CHANGED_MCAST_RATE is introduced in mac80211 to automatically inform all drivers. ath10k can detect this event and forward it via WMI to the driver. The already existing BSS_CHANGED_BASIC_RATES can be used to select the management rate. Without the WMI commands, a low rate (not necessarily one from the basic rates) is used for bcast/mcast/management frames. This means that the /etc/config/wireless settings basic_rate and mcast_rate would have no effect on the rates selected by this driver for the mentioned frames.

Subject: mac80211: ath10k: support for multicast and management rate control
|
||||
|
||||
Drivers with software rate control can directly use the selected multicast
|
||||
rate for multicast/broadcast frames and the minimal basic rate for
|
||||
management frames. But drivers with offloaded rate control algorithms must
|
||||
be informed about such upper layer decisions to configure the
|
||||
hardware/firmware.
|
||||
|
||||
A new BSS_CHANGED_MCAST_RATE is introduced in mac80211 to automatically
|
||||
inform all drivers. ath10k can detect this event and forward it via WMI to
|
||||
the driver. The already existing BSS_CHANGED_BASIC_RATES can be used to
|
||||
select the management rate.
|
||||
|
||||
Without the WMI commands, a low rate (not necessarily one from the basic
|
||||
rates) is used for bcast/mcast/management frames. This means that the
|
||||
/etc/config/wireless settings basic_rate and mcast_rate would have no
|
||||
effect on the rates selected by this driver for the mentioned frames.

+With drivers implementing rate control in driver or firmware

+rate_control_send_low() may not get called, and thus the

|

+Subject: [PATCH] ath10k: add support for configuring management packet rate
|
||||
+
|
||||
+By default the firmware uses 1Mbps and 6Mbps rate for management packets
|
||||
+in 2G and 5G bands respectively. But when the user selects different
|
||||
+basic rates from the userspace, we need to send the management
|
||||
+packets at the lowest basic rate selected by the user.
|
||||
+
|
||||
+This change makes use of WMI_VDEV_PARAM_MGMT_RATE param for configuring the
|
||||
+management packets rate to the firmware.

+Subject: [PATCH] ath10k: fix possible out of bound access of ath10k_rates array
|
||||
+
|
||||
+While using 'ath10k_mac_get_rate_hw_value()' to obtain the hw value
|
||||
+from the passed bitrate, there is a chance of out of bound array access
|
||||
+when wrong bitrate is passed. This is fixed by comparing the bitrates
|
||||
+within the correct size of the ath10k_rates array.
|
||||
+
|
||||
+Fixes commit f279294e9ee2 ("ath10k: add support for configuring management
|
||||
+packet rate"). Also correction made to some indents used in the above commit.

Subject: ath10k-ct: support for multicast and management rate control
|
||||
|
||||
Drivers with software rate control can directly use the selected multicast
|
||||
rate for multicast/broadcast frames and the minimal basic rate for
|
||||
management frames. But drivers with offloaded rate control algorithms must
|
||||
be informed about such upper layer decisions to configure the
|
||||
hardware/firmware.
|
||||
|
||||
A new BSS_CHANGED_MCAST_RATE is introduced in mac80211 to automatically
|
||||
inform all drivers. ath10k-ct can detect this event and forward it via WMI
|
||||
to the driver. The already existing BSS_CHANGED_BASIC_RATES can be used to
|
||||
select the management rate.
|
||||
|
||||
Without the WMI commands, a low rate (not necessarily one from the basic
|
||||
rates) is used for bcast/mcast/management frames. This means that the
|
||||
/etc/config/wireless settings basic_rate and mcast_rate would have no
|
||||
effect on the rates selected by this driver for the mentioned frames.

+Subject: [PATCH] ath10k: add support for configuring management packet rate
|
||||
+
|
||||
+By default the firmware uses 1Mbps and 6Mbps rate for management packets
|
||||
+in 2G and 5G bands respectively. But when the user selects different
|
||||
+basic rates from the userspace, we need to send the management
|
||||
+packets at the lowest basic rate selected by the user.
|
||||
+
|
||||
+This change makes use of WMI_VDEV_PARAM_MGMT_RATE param for configuring the
|
||||
+management packets rate to the firmware.

+Subject: [PATCH] ath10k: fix possible out of bound access of ath10k_rates array
|
||||
+
|
||||
+While using 'ath10k_mac_get_rate_hw_value()' to obtain the hw value
|
||||
+from the passed bitrate, there is a chance of out of bound array access
|
||||
+when wrong bitrate is passed. This is fixed by comparing the bitrates
|
||||
+within the correct size of the ath10k_rates array.
|
||||
+
|
||||
+Fixes commit f279294e9ee2 ("ath10k: add support for configuring management
|
||||
+packet rate"). Also correction made to some indents used in the above commit.
