Pull networking updates from David Miller: "Highlights: 1) Support more Realtek wireless chips, from Jes Sorenson. 2) New BPF types for per-cpu hash and arrap maps, from Alexei Starovoitov. 3) Make several TCP sysctls per-namespace, from Nikolay Borisov. 4) Allow the use of SO_REUSEPORT in order to do per-thread processing of incoming TCP/UDP connections. The muxing can be done using a BPF program which hashes the incoming packet. From Craig Gallek. 5) Add a multiplexer for TCP streams, to provide a messaged based interface. BPF programs can be used to determine the message boundaries. From Tom Herbert. 6) Add 802.1AE MACSEC support, from Sabrina Dubroca. 7) Avoid factorial complexity when taking down an inetdev interface with lots of configured addresses. We were doing things like traversing the entire address less for each address removed, and flushing the entire netfilter conntrack table for every address as well. 8) Add and use SKB bulk free infrastructure, from Jesper Brouer. 9) Allow offloading u32 classifiers to hardware, and implement for ixgbe, from John Fastabend. 10) Allow configuring IRQ coalescing parameters on a per-queue basis, from Kan Liang. 11) Extend ethtool so that larger link mode masks can be supported. From David Decotigny. 12) Introduce devlink, which can be used to configure port link types (ethernet vs Infiniband, etc.), port splitting, and switch device level attributes as a whole. From Jiri Pirko. 13) Hardware offload support for flower classifiers, from Amir Vadai. 14) Add "Local Checksum Offload". Basically, for a tunneled packet the checksum of the outer header is 'constant' (because with the checksum field filled into the inner protocol header, the payload of the outer frame checksums to 'zero'), and we can take advantage of that in various ways.

2016-03-09NFC: microread: Drop platform data header fileJean Delvare
Originally I only wanted to drop the unneeded inclusion of <linux/i2c.h>, but then noticed that struct microread_nfc_platform_data isn't actually used, and MICROREAD_DRIVER_NAME is redefined in the only file where it is used, so we can get rid of the header file and dead code altogether.

2016-03-03NFC: pn544: Drop two useless checks in ACPI probe pathMika Westerberg
When pn544_hci_i2c_acpi_request_resources() gets called we already know that the entries in ->acpi_match_table have matched ACPI ID of the device. In addition I2C client pointer cannot be NULL in any case (otherwise I2C core would not call ->probe() for the driver in the first place). Drop the two useless checks from the driver.

2015-11-18nxp-nci: i2c: Do not check specifically for -EREMOTEIO errorFabio Estevam
Function nxp_nci_i2c_write currently assumes in case of I2C bus NACK that the NFC device is in stand-by mode and will retry the I2C transaction after a pause. This assumes that the first failed I2C transaction will wake-up the device. This is done by checking on EREMOTEIO, which is wrong. According to Documentation/i2c/fault-codes ENXIO shall be used. Unfortunately the NOACK return code is currently inconsistent across various I2C host controller drivers. So only check for the generic error case instead. This is a temporary fix. As soon as all I2C bus master drivers are fixed to consistently return 'ENXIO', then we can do the specific error check again.

2015-10-27NFC: st21nfca: Add support for proprietary commandsChristophe Ricard
Add support for proprietary commands useful mainly for factory testings. Here is a list: - FACTORY_MODE: Allow to set the driver into a mode where no secure element are activated. It does not consider any NFC_ATTR_VENDOR_DATA. - HCI_CLEAR_ALL_PIPES: Allow to execute a HCI clear all pipes command. It does not consider any NFC_ATTR_VENDOR_DATA. - HCI_DM_PUT_DATA: Allow to configure specific CLF registry as for example RF trimmings or low level drivers configurations (I2C, SPI, SWP). - HCI_DM_UPDATE_AID: Allow to configure an AID routing into the CLF routing table following RF technology, CLF mode or protocol. - HCI_DM_GET_INFO: Allow to retrieve CLF information. - HCI_DM_GET_DATA: Allow to retrieve CLF configurable data such as low level drivers configurations or RF trimmings. - HCI_DM_LOAD: Allow to load a firmware into the CLF. A complete packet can be more than 8KB. - HCI_DM_RESET: Allow to run a CLF reset in order to "commit" CLF configuration changes without CLF power off. - HCI_GET_PARAM: Allow to retrieve an HCI CLF parameter (for example the white list). - HCI_DM_FIELD_GENERATOR: Allow to generate different kind of RF technology. When using this command to anti-collision is done. - HCI_LOOPBACK: Allow to echo a command and test the Dh to CLF connectivity.
