Changes: ath10k-ct: Support better RSSI measurements. When used with recent firmware, these changes allow the driver to query per-chain noise-floor from the radio to better calculate the per-chain RSSI. The per-chain RSSI is then summed to provide the 'combined RSSI'. This gives better per-chain RSSI as well as combined RSSI, especially when running with more than 20Mhz bandwidths. Refresh patches.

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.
