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. - -Chipsets Tested : QCA988X, QCA9887, QCA9984 -FW Tested : 10.2.4-1.0-41, 10.4-3.6.104 - -Signed-off-by: Sriram R <srirrama@codeaurora.org> -Signed-off-by: Kalle Valo <kvalo@codeaurora.org> - -Origin: backport, https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=f279294e9ee22a8f306fdc8e4181cf555e6f0f70 ---- ---- a/ath10k-4.19/mac.c -+++ b/ath10k-4.19/mac.c -@@ -157,6 +157,22 @@ u8 ath10k_mac_bitrate_to_idx(const struc - return 0; - } - -+static int ath10k_mac_get_rate_hw_value(int bitrate) -+{ -+ int i; -+ u8 hw_value_prefix = 0; -+ -+ if (ath10k_mac_bitrate_is_cck(bitrate)) -+ hw_value_prefix = WMI_RATE_PREAMBLE_CCK << 6; -+ -+ for (i = 0; i < sizeof(ath10k_rates); i++) { -+ if (ath10k_rates[i].bitrate == bitrate) -+ return hw_value_prefix | ath10k_rates[i].hw_value; -+ } -+ -+ return -EINVAL; -+} -+ - static int ath10k_mac_get_max_vht_mcs_map(u16 mcs_map, int nss) - { - switch ((mcs_map >> (2 * nss)) & 0x3) { -@@ -6413,9 +6429,10 @@ static void ath10k_bss_info_changed(stru - struct cfg80211_chan_def def; - u32 vdev_param, pdev_param, slottime, preamble; - u16 bitrate, hw_value; -- u8 rate; -- int rateidx, ret = 0; -+ u8 rate, basic_rate_idx; -+ int rateidx, ret = 0, hw_rate_code; - enum nl80211_band band; -+ const struct ieee80211_supported_band *sband; - - mutex_lock(&ar->conf_mutex); - -@@ -6621,6 +6638,30 @@ static void ath10k_bss_info_changed(stru - arvif->vdev_id, ret); - } - -+ if (changed & BSS_CHANGED_BASIC_RATES) { -+ if (WARN_ON(ath10k_mac_vif_chan(vif, &def))) { -+ mutex_unlock(&ar->conf_mutex); -+ return; -+ } -+ -+ sband = ar->hw->wiphy->bands[def.chan->band]; -+ basic_rate_idx = ffs(vif->bss_conf.basic_rates) - 1; -+ bitrate = sband->bitrates[basic_rate_idx].bitrate; -+ -+ hw_rate_code = ath10k_mac_get_rate_hw_value(bitrate); -+ if (hw_rate_code < 0) { -+ ath10k_warn(ar, "bitrate not supported %d\n", bitrate); -+ mutex_unlock(&ar->conf_mutex); -+ return; -+ } -+ -+ vdev_param = ar->wmi.vdev_param->mgmt_rate; -+ ret = ath10k_wmi_vdev_set_param(ar, arvif->vdev_id, vdev_param, -+ hw_rate_code); -+ if (ret) -+ ath10k_warn(ar, "failed to set mgmt tx rate %d\n", ret); -+ } -+ - mutex_unlock(&ar->conf_mutex); - } - |
