* qeth: Fold qeth_misc debug areaCarsten Otte2010-06-23
| | | | | | | | | | This patch removes the misc debug area. Instead of logging the entire skb we just log a pointer to it into the card's local debug area in qeth_core_get_next_skb. Other then that, this debug area is not used anywhere. Signed-off-by: Carsten Otte <cotte@de.ibm.com> Signed-off-by: Frank Blaschka <frank.blaschka@de.ibm.com> Signed-off-by: David S.

* qeth: Fold qeth_sense debug areaCarsten Otte2010-06-23
| | | | | | | | | This patch removes the sense debug area completely. Despite the name this debug area makes no sense at all because it's unused completely. Ouch.

* qeth: Fold qeth_trace debug areaCarsten Otte2010-06-23
| | | | | | | | | | | This patch removes the qeth_trace debug area. All relevant data is logged into either qeth_setup or into each card's own debug area. Superfluous information (such as the card number when logging into the card's own debug area) is removed without replacement.

* qeth: Add new s390 debug feature for each qeth cardCarsten Otte2010-06-23
| | | | | | | | | | | | This patch adds a debug area for each qeth card. This debug area will replace various other debug areas that are global for all cards handled by the device driver. On crash dump analysis this makes life easier when trying to find out what's going on with an interface. Also, the forest of debug areas for this device driver is significantly cleared up.

| | | | | | | | | | | | | If another smsgiucv_app device exists, suspend / resume fails with iucv path list corruption, because the same iucv_path_connect is called twice. The patch introduces a flag to save connect status of the smsgiucv path to make sure iucv_path_connect in smsg_pm_restore_thaw is called only once.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The flow id (scd_flow) in a compressed BA packet should match the txq_id of the queue from which the aggregated packets were sent. However, in some hardware like the 1000 series, sometimes the flow id is 0 for the txq_id (10 to 19). This can cause the annoying message: [ 2213.306191] iwlagn 0000:01:00.0: Received BA when not expected [ 2213.310178] iwlagn 0000:01:00.0: Read index for DMA queue txq id (0), index 5, is out of range [0-256] 7 7. And even worse, if agg->wait_for_ba is true when the bad BA is arriving, this can cause system hang due to NULL pointer dereference because the code is operating in a wrong tx queue!
