All BA sessions are destroyed right after reconfig. For devices that manage these in FW, the FW was just reloaded and doesn't know about existing sessions at all. So I guess there's sense in sending the delBA, but no sense calling the driver ampdu callback (at least for how 12xx works). > > FWIW these patches were sitting in my tree as part of a larger set of > changes around the driver ampdu callback to help drivers with internal > queues drop or flush frames appropriately and to react to the different > situations. I didn't think about reconfig at all with this. Yea. These handle other situations. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
