+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.
+
+Chipsets Tested : QCA988X, QCA9887, QCA9984
+FW Tested : 10.2.4-1.0-41, 10.4-3.6.104

+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.
