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.
 | 
						|

						|
