2017-04-03net: hns: Avoid Hip06 chip TX packet line buglipeng
There is a bug on Hip06 that tx ring interrupts packets count will be clear when drivers send data to tx ring, so that the tx packets count will never upgrade to packets line, and cause the interrupts engendered was delayed. Sometimes, it will cause sending performance lower than expected. To fix this bug, we set tx ring interrupts packets line to 1 forever, to avoid count clear. And set the gap time to 20us, to solve the problem that too many interrupts engendered when packets line is 1. This patch could advance the send performance on ARM from 6.6G to 9.37G when an iperf send thread on ARM and an iperf send thread on X86 for XGE.

2017-04-03net: hns: Fix to adjust buf_size of ring according to mtulipeng
Because buf_size of ring set to 2048, the process of rx_poll_one can reuse the page, therefore the performance of XGE can improve. But the chip only supports three bds in one package, so the max mtu is 6K when it sets to 2048. For better performane in litter mtu, we need change buf_size according to mtu. When user change mtu, hns is only change the desc in memory. There are some desc has been fetched by the chip, these desc can not be changed by the code. So it needs set the port loopback and send some packages to let the chip consumes the wrong desc and fetch new desc. Because the Pv660 do not support rss indirection, we need add version check in mtu change process.

SZ_16M PEM resource size includes PEM-specific register and its children resources.

A recent commit introduces a bug in dsi_mgr_phy_enable. In the non dual DSI mode, we reset the mdsi (master DSI) PHY. This isn't right since master and slave DSI exist only in dual DSI mode. For the normal mode of operation, we should simply reset the PHY of the DSI device (i.e. msm_dsi) corresponding to the current bridge. Usage of the wrong DSI pointer also resulted in a static checker warning. That too is resolved with this fix.

2017-04-02iscsi-target: Drop work-around for legacy GlobalSAN initiatorNicholas Bellinger
Once upon a time back in 2009, a work-around was added to support the GlobalSAN iSCSI initiator v3.3 for MacOSX, which during login did not propose nor respond to MaxBurstLength, FirstBurstLength, DefaultTime2Wait and DefaultTime2Retain keys. The work-around in iscsi_check_proposer_for_optional_reply() allowed the missing keys to be proposed, but did not require waiting for a response before moving to full feature phase operation. This allowed GlobalSAN v3.3 to work out-of-the box, and for many years we didn't run into login interopt issues with any other initiators.. Until recently, when Martin tried a QLogic 57840S iSCSI Offload HBA on Windows 2016 which completed login, but subsequently failed with: Got unknown iSCSI OpCode: 0x43 The issue was QLogic MSFT side did not propose DefaultTime2Wait + DefaultTime2Retain, so LIO proposes them itself, and immediately transitions to full feature phase because of the GlobalSAN hack. However, the QLogic MSFT side still attempts to respond to DefaultTime2Retain + DefaultTime2Wait, even though LIO has set ISCSI_FLAG_LOGIN_NEXT_STAGE3 + ISCSI_FLAG_LOGIN_TRANSIT in last login response. So while the QLogic MSFT side should have been proposing these two keys to start, it was doing the correct thing per RFC-3720 attempting to respond to proposed keys before transitioning to full feature phase. All that said, recent versions of GlobalSAN iSCSI (v5.3.0.541) does correctly propose the four keys during login, making the original work-around moot. So in order to allow QLogic MSFT to run unmodified as-is, go ahead and drop this long standing work-around.

2017-04-02hwmon: (lm87) Allow channel data to be set from dts fileMahoda Ratnayaka
Currently there is no method for setting the channel value from the DTS file. When, the driver uses a dts file to initialize the driver platform_data is not set. As a result channel variable may not be set correctly. Without the channel variable set correctly, some of the sensors will not be initialized correctly. For example temp3 sensor sysfs entries. This implements the schema agreed with the device tree binding document.

2017-04-02hwmon: (tmp421) Add OF device ID tableJavier Martinez Canillas
The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:<device>. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF.
