Sorry for the delay in getting back to you. Still care about our
brcmsmac driver, but I can only work one issue at a time.

Did this problem occur with plain 3.2 kernel. I checked out the v3.2
mainline tag and looked at line 2979:ieee80211_rx():
2975:        /*
2976:         * The same happens when we're not even started,
2977:         * but that's worth a warning.
2978:         */
2979:        if (WARN_ON(!local->started))
2980:                goto drop;

I guess brcmsmac is sending up a received wireless packet to mac80211
and it is dropped, because mac80211 did not yet call the start callback.
It is just a warning so if you are having problems connecting to an AP
you may have other issues. As the comment states it is worth a warning
so I will look further into this.
