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) { +@@ -6248,9 +6264,10 @@ 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); + +@@ -6456,6 +6473,30 @@ 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); + } + |
