We talking about multiple phy's and that's when the issue occurs, because we have multiple ieee802154_hw but one global ieee802154_xmit_cb. My patch should define ieee802154_xmit_cb per ieee802154_hw instead. Don't know what's your current issue is. The ieee802154_xmit_cb is protected then by stop/wake queue which garantuees that this struct isn't used twice (in case of multiple interfaces), for multiple phy this is currently a bug. - Alex -- To unsubscribe from this list: send the line "unsubscribe linux-wpan" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
