Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) Brown paper bag fix in HTB scheduler, class options set incorrectly due to a typoe. Fix from Vimalkumar. 2) It's possible for the ipv6 FIB garbage collector to run before all the necessary datastructure are setup during init, defer the notifier registry to avoid this problem. Fix from Michal Kubecek. 3) New i40e ethernet driver from the Intel folks. 4) Add new qmi wwan device IDs, from Bjørn Mork. 5) Doorbell lock in bnx2x driver is not initialized properly in some configurations, fix from Ariel Elior. 6) Revert an ipv6 packet option padding change that broke standardized ipv6 implementation test suites. From Jiri Pirko. 7) Fix synchronization of ARP information in bonding layer, from Nikolay Aleksandrov. 8) Fix missing error return resulting in illegal memory accesses in openvswitch, from Daniel Borkmann. 9) SCTP doesn't signal poll events properly due to mistaken operator precedence, fix also from Daniel Borkmann. 10) __netdev_pick_tx() passes wrong index to sk_tx_queue_set() which essentially disables caching of TX queue in sockets :-/ Fix from Eric Dumazet. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (29 commits) net_sched: htb: fix a typo in htb_change_class() net: qmi_wwan: add new Qualcomm devices ipv6: don't call fib6_run_gc() until routing is ready net: tilegx driver: avoid compiler warning fib6_rules: fix indentation irda: vlsi_ir: Remove casting the return value which is a void pointer irda: donauboe: Remove casting the return value which is a void pointer net: fix multiqueue selection net: sctp: fix smatch warning in sctp_send_asconf_del_ip net: sctp: fix bug in sctp_poll for SOCK_SELECT_ERR_QUEUE net: fib: fib6_add: fix potential NULL pointer dereference net: ovs: flow: fix potential illegal memory access in __parse_flow_nlattrs bcm63xx_enet: remove deprecated IRQF_DISABLED net: korina: remove deprecated IRQF_DISABLED macvlan: Move skb_clone check closer to call qlcnic: Fix warning reported by kbuild test robot. bonding: fix bond_arp_rcv setting and arp validate desync state bonding: fix store_arp_validate race with mode change ipv6/exthdrs: accept tlv which includes only padding bnx2x: avoid atomic allocations during initialization ...

+Linux Base Driver for the Intel(R) Ethernet Controller XL710 Family

+Identifying Your Adapter
+========================
+
+The driver in this release is compatible with the Intel Ethernet
+Controller XL710 Family.
+
+For more information on how to identify your adapter, go to the Adapter &
+Driver ID Guide at:
+
+ http://support.intel.com/support/network/sb/CS-012904.htm
+
+
+Enabling the driver
+===================
+
+The driver is enabled via the standard kernel configuration system,
+using the make command:
+
+ Make oldconfig/silentoldconfig/menuconfig/etc.
+
+The driver is located in the menu structure at:
+
+ -> Device Drivers
+ -> Network device support (NETDEVICES [=y])
+ -> Ethernet driver support
+ -> Intel devices
+ -> Intel(R) Ethernet Controller XL710 Family
+
+Additional Configurations
+=========================
+
+ Generic Receive Offload (GRO)
+ -----------------------------
+ The driver supports the in-kernel software implementation of GRO. GRO has
+ shown that by coalescing Rx traffic into larger chunks of data, CPU
+ utilization can be significantly reduced when under large Rx load. GRO is
+ an evolution of the previously-used LRO interface. GRO is able to coalesce
+ other protocols besides TCP. It's also safe to use with configurations that
+ are problematic for LRO, namely bridging and iSCSI.
+
+ Ethtool
+ -------
+ The driver utilizes the ethtool interface for driver configuration and
+ diagnostics, as well as displaying statistical information. The latest
+ ethtool version is required for this functionality.
+
+ The latest release of ethtool can be found from
+ https://www.kernel.org/pub/software/network/ethtool
+
+ Data Center Bridging (DCB)
+ --------------------------
+ DCB configuration is not currently supported.
+
+ FCoE
+ ----
+ Fiber Channel over Ethernet (FCoE) hardware offload is not currently
+ supported.
+
+ MAC and VLAN anti-spoofing feature
+ ----------------------------------
+ When a malicious driver attempts to send a spoofed packet, it is dropped by
+ the hardware and not transmitted. An interrupt is sent to the PF driver
+ notifying it of the spoof attempt.
+
+ When a spoofed packet is detected the PF driver will send the following
+ message to the system log (displayed by the "dmesg" command):
+
+ Spoof event(s) detected on VF (n)
+
+ Where n=the VF that attempted to do the spoofing.
+
+
+Performance Tuning
+==================
+
+An excellent article on performance tuning can be found at:
+
+http://www.redhat.com/promo/summit/2008/downloads/pdf/Thursday/Mark_Wagner.pdf
+
+
+Known Issues
+============
+
+
+Support
+=======
+
+For general information, go to the Intel support website at:
+
+ http://support.intel.com
+
+or the Intel Wired Networking project hosted by Sourceforge at:
+
+ http://e1000.sourceforge.net
+
+If an issue is identified with the released source code on the supported
+kernel with a supported adapter, email the specific information related
+to the issue to e1000-devel@lists.sourceforge.net and copy
+netdev@vger.kernel.org.
