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.

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:
|
||||
|
||||

|
||||
|
||||
|
||||
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
|
||||

/* Description:
|
||||
* This header file describes the VF-PF communication protocol used
|
||||
* by the various i40e drivers.
|
||||
*
|
||||
* Admin queue buffer usage:
|
||||
* desc->opcode is always i40e_aqc_opc_send_msg_to_pf
|
||||
* flags, retval, datalen, and data addr are all used normally.
|
||||
* Firmware copies the cookie fields when sending messages between the PF and
|
||||
* VF, but uses all other fields internally. Due to this limitation, we
|
||||
* must send all messages as "indirect", i.e. using an external buffer.
|
||||
*
|
||||
* All the vsi indexes are relative to the VF. Each VF can have maximum of
|
||||
* three VSIs. All the queue indexes are relative to the VSI. Each VF can
|
||||
* have a maximum of sixteen queues for all of its VSIs.
|
||||
*
|
||||
* The PF is required to return a status code in v_retval for all messages
|
||||
* except RESET_VF, which does not require any response. The return value is of
|
||||
* i40e_status_code type, defined in the i40e_type.h.
|
||||
*
|
||||
* In general, VF driver initialization should roughly follow the order of these
|
||||
* opcodes. The VF driver must first validate the API version of the PF driver,
|
||||
* then request a reset, then get resources, then configure queues and
|
||||
* interrupts. After these operations are complete, the VF driver may start
|
||||
* its queues, optionally add MAC and VLAN filters, and process traffic.
