Channel active/busy time are showing incorrect(less than previous or sometimes zero) for successive survey dump command. example: Survey data from wlan0 frequency: 5180 MHz [in use] channel active time: 54995 ms channel busy time: 432 ms channel receive time: 0 ms channel transmit time: 59 ms Survey data from wlan0 frequency: 5180 MHz [in use] channel active time: 32592 ms channel busy time: 254 ms channel receive time: 0 ms channel transmit time: 0 ms This patch fix this issue by assigning 'wmi_bss_survey_req_type' as 'WMI_BSS_SURVEY_REQ_TYPE_READ' which accumulate survey data in FW and send survey data to driver upon the driver request. Wrap around is taken care by FW. hardware used : QCA9984 firmware ver : ver 10.4-3.5.3-00057
Have you tested this on other firmwares? I am pretty sure that at least some of them, probably 10.2, will have issues. Maybe you could make this change specific to certain firmware that is known to work with the change? Thanks, Ben
