Add the rt linux 4.1.3-rt3 as base

Import the rt linux 4.1.3-rt3 as OPNFV kvm base.

It's from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git linux-4.1.y-rt and
the base is:

commit 0917f823c59692d751951bf5ea699a2d1e2f26a2
Author: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
Date:   Sat Jul 25 12:13:34 2015 +0200

    Prepare v4.1.3-rt3

    Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

We lose all the git history this way and it's not good. We
should apply another opnfv project repo in future.

+In This Release
+===============
+
+This file describes the Linux* Base Driver for the Intel(R) PRO/100 Family of
+Adapters. This driver includes support for Itanium(R)2-based systems.
+
+For questions related to hardware requirements, refer to the documentation
+supplied with your Intel PRO/100 adapter.
+
+The following features are now available in supported kernels:
+ - Native VLANs
+ - Channel Bonding (teaming)
+ - SNMP
+
+Channel Bonding documentation can be found in the Linux kernel source:
+/Documentation/networking/bonding.txt
+
+
+Identifying Your Adapter
+========================
+
+For more information on how to identify your adapter, go to the Adapter &
+Driver ID Guide at:
+
+  http://support.intel.com/support/network/adapter/pro100/21397.htm
+
+For the latest Intel network drivers for Linux, refer to the following
+website. In the search field, enter your adapter name or type, or use the
+networking link on the left to search for your adapter:
+
+  http://downloadfinder.intel.com/scripts-df/support_intel.asp
+
+Driver Configuration Parameters
+===============================
+
+The default value for each parameter is generally the recommended setting,
+unless otherwise noted.
+
+Rx Descriptors: Number of receive descriptors. A receive descriptor is a data
+   structure that describes a receive buffer and its attributes to the network
+   controller. The data in the descriptor is used by the controller to write
+   data from the controller to host memory. In the 3.x.x driver the valid range
+   for this parameter is 64-256. The default value is 64. This parameter can be
+   changed using the command:
+
+   ethtool -G eth? rx n, where n is the number of desired rx descriptors.
+
+Tx Descriptors: Number of transmit descriptors. A transmit descriptor is a data
+   structure that describes a transmit buffer and its attributes to the network
+   controller. The data in the descriptor is used by the controller to read
+   data from the host memory to the controller. In the 3.x.x driver the valid
+   range for this parameter is 64-256. The default value is 64. This parameter
+   can be changed using the command:
+
+   ethtool -G eth? tx n, where n is the number of desired tx descriptors.
+
+Speed/Duplex: The driver auto-negotiates the link speed and duplex settings by
+   default. The ethtool utility can be used as follows to force speed/duplex.
+
+   ethtool -s eth?  autoneg off speed {10|100} duplex {full|half}
+
+   NOTE: setting the speed/duplex to incorrect values will cause the link to
+   fail.
+
+Event Log Message Level:  The driver uses the message level flag to log events
+   to syslog. The message level can be set at driver load time. It can also be
+   set using the command:
+
+   ethtool -s eth? msglvl n
+
+
+Additional Configurations
+=========================
+
+  Configuring the Driver on Different Distributions
+  -------------------------------------------------
+
+  Configuring a network driver to load properly when the system is started is
+  distribution dependent. Typically, the configuration process involves adding
+  an alias line to /etc/modprobe.d/*.conf as well as editing other system
+  startup scripts and/or configuration files.  Many popular Linux
+  distributions ship with tools to make these changes for you. To learn the
+  proper way to configure a network device for your system, refer to your
+  distribution documentation.  If during this process you are asked for the
+  driver or module name, the name for the Linux Base Driver for the Intel
+  PRO/100 Family of Adapters is e100.
+
+  As an example, if you install the e100 driver for two PRO/100 adapters
+  (eth0 and eth1), add the following to a configuration file in /etc/modprobe.d/
+
+       alias eth0 e100
+       alias eth1 e100
+
+  Viewing Link Messages
+  ---------------------
+  In order to see link messages and other Intel driver information on your
+  console, you must set the dmesg level up to six. This can be done by
+  entering the following on the command line before loading the e100 driver:
+
+       dmesg -n 8
+
+  If you wish to see all messages issued by the driver, including debug
+  messages, set the dmesg level to eight.
+
+  NOTE: This setting is not saved across reboots.
+
+
+  ethtool
+  -------
+
+  The driver utilizes the ethtool interface for driver configuration and
+  diagnostics, as well as displaying statistical information.  The ethtool
+  version 1.6 or later is required for this functionality.
+
+  The latest release of ethtool can be found from
+  http://ftp.kernel.org/pub/software/network/ethtool/
+
+  Enabling Wake on LAN* (WoL)
+  ---------------------------
+  WoL is provided through the ethtool* utility.  For instructions on enabling
+  WoL with ethtool, refer to the ethtool man page.
+
+  WoL will be enabled on the system during the next shut down or reboot. For
+  this driver version, in order to enable WoL, the e100 driver must be
+  loaded when shutting down or rebooting the system.
+
+  NAPI
+  ----
+
+  NAPI (Rx polling mode) is supported in the e100 driver.
+
+  See www.cyberus.ca/~hadi/usenix-paper.tgz for more information on NAPI.
+
+  Multiple Interfaces on Same Ethernet Broadcast Network
+  ------------------------------------------------------
+
+  Due to the default ARP behavior on Linux, it is not possible to have
+  one system on two IP networks in the same Ethernet broadcast domain
+  (non-partitioned switch) behave as expected. All Ethernet interfaces
+  will respond to IP traffic for any IP address assigned to the system.
+  This results in unbalanced receive traffic.
+
+  If you have multiple interfaces in a server, either turn on ARP
+  filtering by
+
+  (1) entering: echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
+      (this only works if your kernel's version is higher than 2.4.5), or
+
+  (2) installing the interfaces in separate broadcast domains (either
+      in different switches or in a switch partitioned to VLANs).
+
