Hello! During testing 5.8.0-rc2 kernel version with Compex WLE900VX card (ath10k) I see following error in dmesg which is periodically repeating, sometimes every second: ath10k_pci 0000:01:00.0: failed to send pdev bss chan info request Card has firmware version 10.1 and features wmi-10.x,has-wmi-mgmt-tx,mfp That error message is located in file ath10k/mac.c in the function ath10k_mac_update_bss_chan_survey(). I checked that 'ret' variable in that function contains value -95 which is -EOPNOTSUPP. It seems that ath10k_wmi_pdev_bss_chan_info_request() is not really supported by firmware 10.1. That function is used only by ath10k_get_survey() function and ath10k_get_survey() ignores all errors from the function ath10k_mac_update_bss_chan_survey(). Which seems wrong as get_survey() could return -EOPNOTSUPP when it is not supported. Could we at least skip printing that error message when 'ret' is -EOPNOTSUPP?
