| * [S390] qdio: fix kernel panic for zfcp 31-bitSteffen Maier2011-12-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The queue_start_poll function pointer field in struct qdio_initialize had to change its type and become a vector of function pointers to support asynchronous delivery of storage blocks so rename the field to make the type change explicit and ensure no other user of qdio tries to use the field the old way. During setting up the qdio queues, only dereference vector elements if the vector is actually allocated.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The NETIUCV device driver allows to connect a Linux guest on z/VM to another z/VM guest based on the z/VM communication facility IUCV. Multiple output paths to different guests are possible, as well as multiple input paths from different guests. With this feature, you can configure multiple point-to-point NETIUCV interfaces between your Linux on System z instance and another z/VM guest.

| | | | | | | | | | | | | | | | | | This patch extends the HiperSockets device driver to send and receive af_iucv traffic over HiperSockets transport. TX: Driver uses new asynchronous delivery of storage blocks to pass flow control/congestion information from the HiperSockets microcode to the af_iucv socket. RX: Memory for incoming traffic is preallocated and passed to HiperSockets layer. If receiver is not capable to clean its buffers shared with HiperSockets and pass new memory to the HiperSockets layer this will cause flow control/congestion events on the sender.

| | | | | | | | | | -Wunused-but-set-variable generates a compile warning for lcs' tasklet function.

| | | | | | | | | | Set rx csum default to hw checksumming again. Remove sysfs interface for rx csum (checksumming) and TSO (large_send). With the new hw_features it does not work to keep the old sysfs interface in parallel. Convert options.checksum_type to new hw_features.

The possibility to call dev_alloc_name in advance remains.
