Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next
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.

63 *
64 *
65 * Note: the brcmfmac can be loaded as module or be statically built-in into
66 * the kernel. If built-in then do note that it uses module_init (and
67 * module_exit) routines which equal device_initcall. So if you intend to
68 * create a module with the platform specific data for the brcmfmac and have
69 * it built-in to the kernel then use a higher initcall then device_initcall
70 * (see init.h). If this is not done then brcmfmac will load without problems
71 * but will not pickup the platform data.
72 *
73 * When the driver does not "detect" platform driver data then it will continue
74 * without reporting anything and just assume there is no data needed. Which is
75 * probably true for most platforms.
76 *
77 * Explanation of the platform_data fields:
78 *
79 * drive_strength: is the preferred drive_strength to be used for the SDIO
80 * pins. If 0 then a default value will be used. This is the target drive
81 * strength, the exact drive strength which will be used depends on the
82 * capabilities of the device.
83 *
84 * oob_irq_supported: does the board have support for OOB interrupts. SDIO
85 * in-band interrupts are relatively slow and for having less overhead on
86 * interrupt processing an out of band interrupt can be used. If the HW
87 * supports this then enable this by setting this field to true and configure
88 * the oob related fields.
89 *
90 * oob_irq_nr, oob_irq_flags: the OOB interrupt information. The values are
91 * used for registering the irq using request_irq function.
92 *
93 * broken_sg_support: flag for broken sg list support of SDIO host controller.
94 * Set this to true if the SDIO host controller has higher align requirement
95 * than 32 bytes for each scatterlist item.
96 *
97 * sd_head_align: alignment requirement for start of data buffer
98 *
99 * sd_sgentry_align: length alignment requirement for each sg entry
100 *
101 * power_on: This function is called by the brcmfmac when the module gets
102 * loaded. This can be particularly useful for low power devices. The platform
103 * spcific routine may for example decide to power up the complete device.
104 * If there is no use-case for this function then provide NULL.
105 *
106 * power_off: This function is called by the brcmfmac when the module gets
107 * unloaded. At this point the device can be powered down or otherwise be reset.
108 * So if an actual power_off is not supported but reset is then reset the device
109 * when this function gets called. This can be particularly useful for low power
110 * devices. If there is no use-case for this function (either power-down or
111 * reset) then provide NULL.
112 *
113 * reset: This function can get called if the device communication broke down.
114 * This functionality is particularly useful in case of SDIO type devices. It is
115 * possible to reset a dongle via sdio data interface, but it requires that
116 * this is fully functional. This function is chip/module specific and this
117 * function should return only after the complete reset has completed.
