2014-06-19wil6210: fix for unreachable code in wmi_recv_cmdVladimir Kondratiev1-15/+10
As reported by Dan Carpenter <[email protected]>: The patch a715c7ddd65a: "wil6210: improve debug for WMI receive" from May 29, 2014, leads to the following static checker warning: drivers/net/wireless/ath/wil6210/wmi.c:746 wmi_recv_cmd() info: ignoring unreachable code. drivers/net/wireless/ath/wil6210/wmi.c 739 spin_unlock_irqrestore(&wil->wmi_ev_lock, flags); 740 { 741 int q = queue_work(wil->wmi_wq, 742 &wil->wmi_event_worker); 743 wil_dbg_wmi(wil, "queue_work -> %d\n", q); 744 } 745 } 746 if (n > 1) ^^^^^^^^^^ We never reach this if statemtent. 747 wil_dbg_wmi(wil, "%s -> %d events processed\n", __func__, n); 748 } Exit loop with "break", not "return".

2014-06-19wil6210: fix disconnect handling for APVladimir Kondratiev1-5/+13
For the AP-like interface, if "disconnect all" requested, every station should be deleted with cfg80211_del_sta(). Implement this behavior. Signed-off-by: Vladimir Kondratiev <[email protected]> Signed-off-by: John W. Linville <[email protected]>
2014-06-19wil6210: avoid dmesg pollution by Tx errorsVladimir Kondratiev1-2/+2
On Tx path, when vring for the destination not found, it was considered as error and message was printed unconditionally. However, this situation is normal after disconnect. If disconnect was while heavy traffic load, lots of Tx packets will be dropped and this would cause significant amount of prints in dmesg. Demote messages priority from 'error' to 'debug'.

2014-06-19wil6210: Tx performance monitoringVladimir Kondratiev3-4/+23
For performance monitoring, trace time intervals when Tx vring is idle/not idle. Use CPU cycle counter for this, because jiffies is too rough, and other precise time measurement methods involve overhead while get_cycles() should be fast. This used to provide some estimation for percentage when Tx vring was idle, i.e. when hardware is under-utilized. Estimation is not precise because of many reasons - CPU frequency scaling, grt_cycles() may be per core etc. But still, it is good estimation Signed-off-by: Vladimir Kondratiev <[email protected]> Signed-off-by: John W. Linville <[email protected]>
