Wrap around is taken care by FW. hardware used : QCA9984 firmware ver : ver 10.4-3.5.3-00057 Signed-off-by: Venkateswara Naralasetty --- v2: * updated commit log. drivers/net/wireless/ath/ath10k/mac.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/net/wireless/ath/ath10k/mac.c b/drivers/net/wireless/ath/ath10k/mac.c index f068e2b..db93ab1 100644 --- a/drivers/net/wireless/ath/ath10k/mac.c +++ b/drivers/net/wireless/ath/ath10k/mac.c @@ -6837,7 +6837,7 @@ ath10k_mac_update_bss_chan_survey(struct ath10k *ar, struct ieee80211_channel *channel) { int ret; - enum wmi_bss_survey_req_type type = WMI_BSS_SURVEY_REQ_TYPE_READ_CLEAR; + enum wmi_bss_survey_req_type type = WMI_BSS_SURVEY_REQ_TYPE_READ; lockdep_assert_held(&ar->conf_mutex); -- 2.7.4
