This is primarily a Bluetooth pull. Gustavo says: "A lot of patches to 3.17. The bulk of changes here are for LE support. The 6loWPAN over Bluetooth now has it own module, we also have support for background auto-connection and passive scanning, Bluetooth device address provisioning, support for reading Bluetooth clock values and LE connection parameters plus many many fixes."

2014-07-11ipv6: addrconf: implement address generation modesJiri Pirko
This patch introduces a possibility for userspace to set various (so far two) modes of generating addresses. This is useful for example for NetworkManager because it can set the mode to NONE and take care of link local addresses itself. That allow it to have the interface up, monitoring carrier but still don't have any addresses on it. One more use-case by Dan Williams: <quote> WWAN devices often have their LL address provided by the firmware of the device, which sometimes refuses to respond to incorrect LL addresses when doing DHCPv6 or IPv6 ND. The kernel cannot generate the correct LL address for two reasons: 1) WWAN pseudo-ethernet interfaces often construct a fake MAC address, or read a meaningless MAC address from the firmware. Thus the EUI64 and the IPv6LL address the kernel assigns will be wrong. The real LL address is often retrieved from the firmware with AT or proprietary commands. 2) WWAN PPP interfaces receive their LL address from IPV6CP, not from kernel assignments. Only after IPV6CP has completed do we know the LL address of the PPP interface and its peer. But the kernel has already assigned an incorrect LL address to the interface. So being able to suppress the kernel LL address generation and assign the one retrieved from the firmware is less complicated and more robust. </quote> Signed-off-by: Jiri Pirko <jiri@resnulli.us> Signed-off-by: David S.

2014-07-10Merge branch 'mvebu'David S. Miller
Ezequiel Garcia says: ==================== Network driver for Armada 375 SoC This is the fourth round of the Armada 375 network support patchset. I've tried to address all the feedback provided for last version and I hope the driver looks better now. If there's nothing else to fix, we'd like to merge this for v3.17. The first patch should go through the network tree, and the other patches through the mvebu tree. Thanks a lot for all the great review, and feel free to comment some more! Changes from v3: * Further optimization of the MTU, MAC and ring parameter change to make it smoothier. * Lots of cleanups in the parser configuration code, most of them addressing the feedback from Francois. This include fixing: missing curly braces, excessive parenthesis, excessive scope, and making several functions more readable. * Removed the Rx/Tx queue number module parameter. There's no reason to use any other than the default hardware-defined value. Changes from v2: * Reworked mvpp2_prs_tcam_first_free() as suggested by Joe and Francois, to have a single loop instead of two. * Replaced mvpp2_cpu_interrupts_enable/disable(pp, cpu) with one function that enables/disable interrupts on all the CPUs at once. * Factor out Tx descriptor DMA unmap + descriptor put sequence to have more readable code, as suggested by Francois. * Remove redundant netif_running() checks in the ingress and egress path, as suggested by Francois. * Reworked ring parameter, MTU and MAC address setting to produce a more gentle modification of the parameter, and have a fallback in the event of a failure. * Fixed a percpu memory leak on error path, also noted by Francois. * Removed the usage of the legacy net_device irq field, requested by Francois. * Removed the unneeded multiple Tx port support. It was hardcoded to a single Tx port in the previous version so we decided to drop it and simplify the code. * Optimize the on_each_cpu() calls to clear the sent counters and the TX_DONE pkts coalescing setting. on_each_cpu is expensive so it's better to minize the calls to it. Changes from v1: * Marcin Wojtas is the author of the driver, so I fixed authorship for patch 1/3: "ethernet: Add new driver for Marvell Armada 375 network unit" This patchset adds a new network driver to support the network controller in Armada 375 SoC. The network interfaces share a common hardware unit called Packet Processor, which contains a common register space and per-port register spaces. The new network unit has different RXQ and TXQ management. The ports associate so-called per-port "logical queues" which are mapped to "physical queues". The latter are shared among the ports. Fo the egress part, the mapping for each port is predefined by hardware. The egress path incorporates so-called aggregation queues (one per CPU), from where the data is passed to the physical queues and then via prefetch buffer to the TxDMA. The ingress path has a Parser and Classifier (PnC) and a Buffer Manager (BM) whose usage is obligatory. We are only implementing a simple configuration for the Parser and Classifier, yet the code is considerably large. This network unit has other optional features like xPON, WoL, Hardware Forwarding, and more. This initial commit doesn't provide support for these. The mvpp2 network driver has been written by Marcin Wojtas and then reviewed and cleaned up by Ezequiel Garcia. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Given the controller is very different from the ones in the other Marvell SoCs that use the mv643xx_eth (Kirkwood, Orion, Discovery) and mvneta (Armada 370/38x/XP) drivers, a new driver is needed.
