2011-11-16qeth: Reduce CPU consumption through less SIGA-r callsEinar Lueck
Patch avoids SIGA-r calls in case of SIGA-r required. It only calls SIGA-r if a threshold of free buffer is reached. CPU consumption is reduced as a consequence.

2011-11-16netiucv: reinsert dev_alloc_name for device namingUrsula Braun
Invocation of dev_alloc_name() is re-inserted, because the created net_device name is used to create the device name for the iucv bus. This device is created before the register_netdev call.

2011-11-16qeth: remove WARN_ON leftoverChristian Borntraeger
The patch "qeth: exploit asynchronous delivery of storage blocks" added a WARN_ON in qeth_schedule_recovery. A device recovery should not cause a kernel warning.

2011-10-30[S390] fix mismatch in summation of I/O IRQ statisticsPeter Oberparleiter
Current IRQ statistics support does not show detail counts for I/O interrupts which are processed internally only. The result is a summation count which is way off such as this one: CPU0 CPU1 CPU2 I/O: 1331 710 442 [...] QAI: 15 16 16 [I/O] QDIO Adapter Interrupt QDI: 1 0 0 [I/O] QDIO Interrupt DAS: 706 645 381 [I/O] DASD C15: 26 10 0 [I/O] 3215 C70: 0 0 0 [I/O] 3270 TAP: 0 0 0 [I/O] Tape VMR: 0 0 0 [I/O] Unit Record Devices LCS: 0 0 0 [I/O] LCS CLW: 0 0 0 [I/O] CLAW CTC: 0 0 0 [I/O] CTC APB: 0 0 0 [I/O] AP Bus Fix this by moving I/O interrupt accounting into the common I/O layer.

2011-08-13qeth: add support for af_iucv HiperSockets transportFrank Blaschka
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.

The threshold is specific by the drivers because a Hipersockets device is much faster in utilizing outbound buffers than a ZFCP or OSA device.
