2018-03-30liquidio: prevent rx queues from getting stalledRaghu Vatsavayi
This commit has fix for RX traffic issues when we stress test the driver with continuous ifconfig up/down under very high traffic conditions. Reason for the issue is that, in existing liquidio_stop function NAPI is disabled even before actual FW/HW interface is brought down via send_rx_ctrl_cmd(lio, 0). Between time frame of NAPI disable and actual interface down in firmware, firmware continuously enqueues rx traffic to host. When interrupt happens for new packets, host irq handler fails in scheduling NAPI as the NAPI is already disabled. After "ifconfig <iface> up", Host re-enables NAPI but cannot schedule it until it receives another Rx interrupt. Host never receives Rx interrupt as it never cleared the Rx interrupt it received during interface down operation. NIC Rx interrupt gets cleared only when Host processes queue and clears the queue counts. Above anomaly leads to other issues like packet overflow in FW/HW queues, backpressure. Fix: This commit fixes this issue by disabling NAPI only after informing firmware to stop queueing packets to host via send_rx_ctrl_cmd(lio, 0). send_rx_ctrl_cmd is not visible in the patch as it is already there in the code. The DOWN command also waits for any pending packets to be processed by NAPI so that the deadlock will not occur.

2018-03-30nfp: flower: offload phys port MTU changeJohn Hurley
Trigger a port mod message to request an MTU change on the NIC when any physical port representor is assigned a new MTU value. The driver waits 10 msec for an ack that the FW has set the MTU. If no ack is received the request is rejected and an appropriate warning flagged. Rather than maintain an MTU queue per repr, one is maintained per app. Because the MTU ndo is protected by the rtnl lock, there can never be contention here. Portmod messages from the NIC are also protected by rtnl so we first check if the portmod is an ack and, if so, handle outside rtnl and the cmsg work queue. Acks are detected by the marking of a bit in a portmod response. They are then verfied by checking the port number and MTU value expected by the app. If the expected MTU is 0 then no acks are currently expected. Also, ensure that the packet headroom reserved by the flower firmware is considered when accepting an MTU change on any repr.

2018-03-30cpufreq: CPPC: Use transition_delay_us depending transition_latencyGeorge Cherian
With commit e948bc8fbee0 (cpufreq: Cap the default transition delay value to 10 ms) the cpufreq was not honouring the delay passed via ACPI (PCCT). Due to which on ARM based platforms using CPPC the cpufreq governor tries to change the frequency of CPUs faster than expected. This leads to continuous error messages like the following. " ACPI CPPC: PCC check channel failed. Status=0 " Earlier (without above commit) the default transition delay was taken form the value passed from PCCT. Use the same value provided by PCCT to set the transition_delay_us.

2018-03-30mtd: fsl-quadspi: Distinguish the mtd device namesFabio Estevam
Currently on a imx6sx-sdb board, which has two SPI NOR chips connected to QSPI2 the following output from /proc/mtd is seen: dev: size erasesize name mtd0: 01000000 00010000 "21e4000.qspi" mtd1: 01000000 00010000 "21e4000.qspi" Attempts to partition them on the kernel command line result in both chips with identical (and identically named) partitions, which is an inconvenient behavior. Assign a different mtd->name for each mtd device to avoid this problem. After this change the output from /proc/mtd becomes: dev: size erasesize name mtd0: 01000000 00010000 "21e4000.qspi-0" mtd1: 01000000 00010000 "21e4000.qspi-1" In order to keep mtdparts compatibility keep the mtd->name unchanged when a single SPI NOR is present.
