Description David Hill 2011-06-23 21:09:22 UTC 
Hi guys,

    The following 2 lines are shown every minutes in syslog:
 ieee80211 ph0: wl_ops_bss_info_changed: BSS idle: true (implement)
 ieee80211 ph0: wl_ops_bss_info_changed: BSS idle: false (implement)


This is caused by the following lines:
        if (changed & BSS_CHANGED_IDLE) {
                /* Idle changed for this BSS/interface */
                wiphy_err(wiphy, "%s: BSS idle: %s (implement)\n", __func__,
                          info->idle ? "true" : "false");
        }


Once a wireless connection is started, those messages disappear.

This seems to be a bug in the broadcom driver, not wl12xx.  The file in question is this:

drivers/staging/brcm80211/brcmsmac/wl_mac80211.c

I don't know who this bug should be assigned to, but I don't think it's me. :)

Ooops -- sorry!
Comment 3 Luca 2011-06-26 15:30:37 UTC 
Just as a side-note to the new bug owner, we get out of idle when we start scanning, so this warning seems wrong.  I guess this explains why this happens every minute, most likely network-manager, connman or some other userspace application is starting a scan regularly.

I started investigating this.
Comment 5 Roland Vossen 2011-06-29 12:16:12 UTC 
Problem solved, patch to appear as part of a patch train shortly.
