This is used mainly for mesh metric calculation. Signed-off-by: Maxim Altshul --- Changed the units of returned value. drv_get_expected_throughput returns units of Kbps by definition, and thus we must comply as well. Mbps * 1000 = Kbps. drivers/net/wireless/ti/wlcore/main.c | 15 +++++++++++++++ 1 file changed, 15 insertions(+) diff --git a/drivers/net/wireless/ti/wlcore/main.c b/drivers/net/wireless/ti/wlcore/main.c index 39dec7d..cb1103b 100644 --- a/drivers/net/wireless/ti/wlcore/main.c +++ b/drivers/net/wireless/ti/wlcore/main.c @@ -5851,6 +5851,20 @@ out: mutex_unlock(&wl->mutex); } +static u32 wlcore_op_get_expected_throughput(struct ieee80211_sta *sta) +{ + struct wl1271_station *wl_sta = (struct wl1271_station *)sta->drv_priv; + struct wl1271 *wl = wl_sta->wl; + u8 hlid = wl_sta->hlid; + u32 ret = 0; + + /* return in units of Kbps */ + if (wl) + ret = (wl->links[hlid].fw_rate_mbps * 1000); + + return ret; +} + static bool wl1271_tx_frames_pending(struct ieee80211_hw *hw) { struct wl1271 *wl = hw->priv; @@ -6051,6 +6065,7 @@ static const struct ieee80211_ops wl1271_ops = { .switch_vif_chanctx = wlcore_op_switch_vif_chanctx, .sta_rc_update = wlcore_op_sta_rc_update, .sta_statistics = wlcore_op_sta_statistics, + .get_expected_throughput = wlcore_op_get_expected_throughput, CFG80211_TESTMODE_CMD(wl1271_tm_cmd) }; -- 2.9.0
