The driver, under certain conditions, spews log messages like this: wl0: wlc_d11hdrs_mac80211: AC_BE txop exceeded phylen 159/256 dur 1778/1504 These log messages turned out to be false alarms. Root cause was that the AC was derived from the sk_buff::priority field. Fix was to derive the AC from the sk_buff using skb_get_queue_mapping() Signed-off-by: Roland Vossen Tested-by: Larry Finger Acked-by: Larry Finger Signed-off-by: Greg Kroah-Hartman --- diff --git a/drivers/staging/brcm80211/brcmsmac/wlc_main.c b/drivers/staging/brcm80211/brcmsmac/wlc_main.c index 639b5d7c9603..181a626d1984 100644 --- a/drivers/staging/brcm80211/brcmsmac/wlc_main.c +++ b/drivers/staging/brcm80211/brcmsmac/wlc_main.c @@ -6283,7 +6283,7 @@ wlc_d11hdrs_mac80211(struct wlc_info *wlc, struct ieee80211_hw *hw, ((preamble_type[1] == WLC_MM_PREAMBLE) == (txh->MModeFbrLen != 0))); - ac = wme_fifo2ac[queue]; + ac = skb_get_queue_mapping(p); if (SCB_WME(scb) && qos && wlc->edcf_txop[ac]) { uint frag_dur, dur, dur_fallback;
