Helmut expressed some concerns wrt such drivers, in + particular DELBAs in rt2x00. + + ATM, DELBAs are sent after a driver has called (hence "purposely") + ieee80211_start_tx_ba_cb_irqsafe and Johannes and Emmanuel gave some + details wrt intentions behind the split of the IEEE80211_AMPDU_TX_STOP_* + given to the driver ampdu_action supposed to call this function, which + could prove handy to people trying to do the right thing in faulty + drivers (if their fw/hw don't get in their way). + + [1] http://mid.gmane.org/1390391564-18481-1-git-send-email-karl.beldan@gmail.com + [2] Commit: cf6bb79ad828 ("mac80211: Use appropriate TID for sending BAR, ADDBA and DELBA frames") + + Signed-off-by: Karl Beldan + Cc: Helmut Schaa + Cc: Emmanuel Grumbach + Signed-off-by: Johannes Berg +--- a/drivers/net/wireless/ath/ath6kl/cfg80211.c ++++ b/drivers/net/wireless/ath/ath6kl/cfg80211.c +@@ -790,7 +790,7 @@ void ath6kl_cfg80211_connect_event(struc + if (nw_type & ADHOC_NETWORK) { + ath6kl_dbg(ATH6KL_DBG_WLAN_CFG, "ad-hoc %s selected\n", + nw_type & ADHOC_CREATOR ?
