The dev->dma_mask usually points to dev->coherent_dma_mask. This is an issue as setting both of them will override the other. This is problematic here as the PPv2 driver uses a 32-bit-mask for coherent accesses (txq, rxq, bm) and a 40-bit mask for all other accesses due to an hardware limitation.

[PATCH net-next 7/9] s390/qeth: translate SETVLAN/DELVLAN errors

Properly return any error encountered during VLAN processing to the the caller. Resulting change in behaviour: if SETVLAN fails while registering a new VLAN ID, the stack no longer creates the corresponding vlan device. Signed-off-by: Julian Wiedmann Reviewed-by: Ursula

[PATCH net-next 5/9] s390/qeth: don't take queue lock in send_packet_fast()

Locking the output queue prior to TX is needed on OSA devices, to synchronize against a packing flush from the TX completion code (via qeth_check_outbound_queue()). But send_packet_fast() is only used for IQDs, which don't do packing. So remove the locking, and apply some easy cleanups.

[PATCH net-next 3/9] s390/qeth: add VNICC get/set timeout support

From: Hans Wippel HiperSockets allow configuring so called VNIC Characteristics (VNICC) that influence how the underlying hardware handles packets. For VNICCs, additional commands for getting and setting timeouts are available. Currently, the learning VNICC uses these

[PATCH net-next 8/9] s390/qeth: fold VLAN handling into l3_rebuild_skb()

[PATCH net-next 1/9] s390/qeth: add basic VNICC support

From: Hans Wippel VNIC Characteristics (VNICC) are features of HiperSockets that define how packets are handled by the underlying network hardware. For example, if the VNICC flooding is configured on a qeth device, ethernet frames to unknown destination MAC addresses

[PATCH net-next 2/9] s390/qeth: add VNICC enable/disable support
