Subject: [PATCH] staging: brcm80211: fix for 'AC_BE txop..' logs spammed problem Date: Fri, 25 Mar 2011 02:23:08 -0700 From: Roland Vossen <rvossen@xxxxxxxxxxxx> To: =Larry.Finger@xxxxxxxxxxxx <=Larry.Finger@xxxxxxxxxxxx>, gregkh@xxxxxxx <gregkh@xxxxxxx> CC: devel@xxxxxxxxxxxxxxxxxxxxxx <devel@xxxxxxxxxxxxxxxxxxxxxx> Larry Finger reported this issue. 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 <rvossen@xxxxxxxxxxxx>
Tested-by: Larry Finger <Larry.Finger@xxxxxxxxxxxx> and an obvious ACK. Larry
