Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next
Pull networking updates from David Miller: "Here is my initial pull request for the networking subsystem during this merge window: 1) Support for ESN in AH (RFC 4302) from Fan Du. 2) Add full kernel doc for ethtool command structures, from Ben Hutchings. 3) Add BCM7xxx PHY driver, from Florian Fainelli. 4) Export computed TCP rate information in netlink socket dumps, from Eric Dumazet. 5) Allow IPSEC SA to be dumped partially using a filter, from Nicolas Dichtel. 6) Convert many drivers to pci_enable_msix_range(), from Alexander Gordeev. 7) Record SKB timestamps more efficiently, from Eric Dumazet. 8) Switch to microsecond resolution for TCP round trip times, also from Eric Dumazet. 9) Clean up and fix 6lowpan fragmentation handling by making use of the existing inet_frag api for it's implementation. 10) Add TX grant mapping to xen-netback driver, from Zoltan Kiss. 11) Auto size SKB lengths when composing netlink messages based upon past message sizes used, from Eric Dumazet. 12) qdisc dumps can take a long time, add a cond_resched(), From Eric Dumazet. 13) Sanitize netpoll core and drivers wrt. SKB handling semantics. Get rid of never-used-in-tree netpoll RX handling. From Eric W Biederman. 14) Support inter-address-family and namespace changing in VTI tunnel driver(s). From Steffen Klassert. 15) Add Altera TSE driver, from Vince Bridgers. 16) Optimizing csum_replace2() so that it doesn't adjust the checksum by checksumming the entire header, from Eric Dumazet. 17) Expand BPF internal implementation for faster interpreting, more direct translations into JIT'd code, and much cleaner uses of BPF filtering in non-socket ocntexts. From Daniel Borkmann and Alexei Starovoitov" * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1976 commits) netpoll: Use skb_irq_freeable to make zap_completion_queue safe. net: Add a test to see if a skb is freeable in irq context qlcnic: Fix build failure due to undefined reference to `vxlan_get_rx_port' net: ptp: move PTP classifier in its own file net: sxgbe: make "core_ops" static net: sxgbe: fix logical vs bitwise operation net: sxgbe: sxgbe_mdio_register() frees the bus Call efx_set_channels() before efx->type->dimension_resources() xen-netback: disable rogue vif in kthread context net/mlx4: Set proper build dependancy with vxlan be2net: fix build dependency on VxLAN mac802154: make csma/cca parameters per-wpan mac802154: allow only one WPAN to be up at any given time net: filter: minor: fix kdoc in __sk_run_filter netlink: don't compare the nul-termination in nla_strcmp can: c_can: Avoid led toggling for every packet. can: c_can: Simplify TX interrupt cleanup can: c_can: Store dlc private can: c_can: Reduce register access can: c_can: Make the code readable ...

+* Broadcom BCM7xxx Ethernet Controller (GENET)
+
+Required properties:
+- compatible: should contain one of "brcm,genet-v1", "brcm,genet-v2",
+ "brcm,genet-v3", "brcm,genet-v4".
+- reg: address and length of the register set for the device
+- interrupts: must be two cells, the first cell is the general purpose
+ interrupt line, while the second cell is the interrupt for the ring
+ RX and TX queues operating in ring mode
+- phy-mode: see ethernet.txt file in the same directory
+- #address-cells: should be 1
+- #size-cells: should be 1
+
+Optional properties:
+- clocks: When provided, must be two phandles to the functional clocks nodes
+ of the GENET block. The first phandle is the main GENET clock used during
+ normal operation, while the second phandle is the Wake-on-LAN clock.
+- clock-names: When provided, names of the functional clock phandles, first
+ name should be "enet" and second should be "enet-wol".
+
+- phy-handle: See ethernet.txt file in the same directory; used to describe
+ configurations where a PHY (internal or external) is used.
+
+- fixed-link: When the GENET interface is connected to a MoCA hardware block or
+ when operating in a RGMII to RGMII type of connection, or when the MDIO bus is
+ voluntarily disabled, this property should be used to describe the "fixed link".
+ See Documentation/devicetree/bindings/net/fsl-tsec-phy.txt for information on
+ the property specifics
+
+Required child nodes:
+
+- mdio bus node: this node should always be present regarless of the PHY
+ configuration of the GENET instance
+
+MDIO bus node required properties:
+
+- compatible: should contain one of "brcm,genet-mdio-v1", "brcm,genet-mdio-v2"
+ "brcm,genet-mdio-v3", "brcm,genet-mdio-v4", the version has to match the
+ parent node compatible property (e.g: brcm,genet-v4 pairs with
+ brcm,genet-mdio-v4)
+- reg: address and length relative to the parent node base register address
+- #address-cells: address cell for MDIO bus addressing, should be 1
+- #size-cells: size of the cells for MDIO bus addressing, should be 0

+Ethernet PHY node properties:
+
+See Documentation/devicetree/bindings/net/phy.txt for the list of required and
+optional properties.
