From: Jason Andryuk <jandryuk@xxxxxxxxx> With the latest mac80211 stack, the driver needs to be updated for cfg80211 scanning. I based the changes off of modifications for at76_usb found here: http://johannes.sipsolutions.net/patches/old/all/2008-09-19-13:35/020-cfg80211-scan.patch The trick was that max_signal also needs to be set to avoid a divide by zero Oops. I just guessed and used the value 100 for now. kvalo: handpicked the change from two different patches Signed-off-by: Jason Andryuk <jandryuk@xxxxxxxxx> Signed-off-by: Kalle Valo <kalle.valo@xxxxxx> --- drivers/net/wireless/at76c50x-usb.c | 24 ++++++++++++++++++------ 1 files changed, 18 insertions(+), 6 deletions(-) diff --git a/drivers/net/wireless/at76c50x-usb.c b/drivers/net/wireless/at76c50x-usb.c index e8868ae..df3efc5 100644 --- a/drivers/net/wireless/at76c50x-usb.c +++ b/drivers/net/wireless/at76c50x-usb.c @@ -1861,7 +1861,7 @@ static void at76_dwork_hw_scan(struct work_struct *work) goto exit; } - ieee80211_scan_completed(priv->hw); + ieee80211_scan_completed(priv->hw, false); if (is_valid_ether_addr(priv->bssid)) at76_join(priv); @@ -1872,14 +1872,15 @@ exit: mutex_unlock(&priv->mtx); } -static int at76_hw_scan(struct ieee80211_hw *hw, u8 *ssid, size_t len) +static int at76_hw_scan(struct ieee80211_hw *hw, + struct cfg80211_scan_request *req) { struct at76_priv *priv = hw->priv; struct at76_req_scan scan; - int ret; + u8 *ssid = NULL; + int ret, len = 0; at76_dbg(DBG_MAC80211, "%s():", __func__); - at76_dbg_dump(DBG_MAC80211, ssid, len, "ssid %zd bytes:", len); mutex_lock(&priv->mtx); @@ -1887,11 +1888,20 @@ static int at76_hw_scan(struct ieee80211_hw *hw, u8 *ssid, size_t len) memset(&scan, 0, sizeof(struct at76_req_scan)); memset(scan.bssid, 0xFF, ETH_ALEN); - scan.scan_type = SCAN_TYPE_ACTIVE; - if (priv->essid_size > 0) { + + if (req->n_ssids) { + scan.scan_type = SCAN_TYPE_ACTIVE; + ssid = req->ssids[0].ssid; + len = req->ssids[0].ssid_len; + } else { + scan.scan_type = SCAN_TYPE_PASSIVE; + } + + if (len) { memcpy(scan.essid, ssid, len); scan.essid_size = len; } + scan.min_channel_time = cpu_to_le16(priv->scan_min_time); scan.max_channel_time = cpu_to_le16(priv->scan_max_time); scan.probe_delay = cpu_to_le16(priv->scan_min_time * 1000); @@ -2217,10 +2227,12 @@ static int at76_init_new_device(struct at76_priv *priv, priv->scan_mode = SCAN_TYPE_ACTIVE; /* mac80211 initialisation */ + priv->hw->wiphy->max_scan_ssids = 1; priv->hw->wiphy->interface_modes = BIT(NL80211_IFTYPE_STATION); priv->hw->wiphy->bands[IEEE80211_BAND_2GHZ] = &at76_supported_band; priv->hw->flags = IEEE80211_HW_RX_INCLUDES_FCS | IEEE80211_HW_SIGNAL_UNSPEC; + priv->hw->max_signal = 100; SET_IEEE80211_DEV(priv->hw, &interface->dev); SET_IEEE80211_PERM_ADDR(priv->hw, priv->mac_addr); -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
