Great to see you on board!

Thank you to contribute a new driver.

It looks like you're trying to use the BSD 2 clause license from here.  Can you
please grab the properly formatted copy from someplace like here:
http://opensource.org/licenses/BSD-2-Clause

So that its clear.  I think it should just call out the clauses more
clearly.

Thanks
Neil

Don't include this change until last in the series, as you haven't patched in
this directory yet.  Otherwise you'll get a failed to build problem.

Make this the last patch in your series, and merge it with the chunk from the
last patch that adds the enic directory to the lib/Makefile, so that a bisect
will build between these commits.

Many informations in the release notes are not well adapted to an integration.
Please could you rework it?
I'd like to create a doc directory for drivers (doc/drivers) as doc/guides.
So this doc should be in rst format in order to be processed by sphinx and
published on the web site (like guides).
Could you also include a performance test report based on testpmd?

Thanks a lot

Hi Neil,

Thanks for the comments.  I shall work on the modifications that you have
suggested and get back with V2.

Sujith,

It seems that this PMD is based on DPDK 1.7.
Could you rebase it on HEAD?

What is the status of these files?
Are they copied from somewhere?
Please explain in the commit log.

Could you move them in a subdirectory vnic/ or base/?

Please could you remove the src/ subdirectory level?

Thanks

Hi Thomas,

Thank you for the comments.
I¹ll work on moving the release notes to rst and add performance numbers
with testpmd.  Once I fix these and Neil¹s comments, I shall get back with
version 2.

Thanks,

+================================================================================
+         DPDK Poll-mode Driver for Cisco Systems Inc. VIC Ethernet NIC
+                                 Release Notes
+                                Version 1.0.0.3
+================================================================================
+  ENIC PMD is the poll-mode driver for the Cisco System Inc. VIC Ethernet NIC
+  to be used with DPDK suite.
+
+  If you are running/would like to run your applications on Intel DPDK software 
+  suite on Cisco UCS servers that use Cisco VIC adapters, please read the 
+  information provided in this document.
+
+How to obtain ENIC PMD integrated DPDK?
+---------------------------------------
+  The source tarball of the whole DPDK suite, dpdk-<version>.tar.gz could be 
+  downloaded from www.dpdk.org
+
+  Alternatively, the same could be downloaded from www.cisco.com.  
+
+
+Software License
+----------------
+  Please read the file LICENSE in lib/librte_pmd_enic/ directory in DPDK 
+  source tree.
+
+  The License terms are also present at the top of the source files.
+
+
+Configuration information
+-------------------------
+  In order to ensure that ENIC PMD will also be built by DPDK build scripts, 
+  ensure that CONFIG_RTE_LIBRTE_ENIC_PMD=y is there in the following file in 
+  DPDK suite.
+
+  - config/common_linuxapp
+
+  If CONFIG_RTE_EAL_VFIO is y in config/common/linuxapp in the DPDK source
+  tree, ENIC PMD will try to get initialized using VFIO.  If
+  CONFIG_RTE_EAL_VFIO is n, it will try to use UIO framework.
+
+  No matter how many receive/transmit queues are configured in the service
+  profile, only one interrupt per vNIC interface needs to be configured.
+  ENIC PMD uses this interrupt to get information about errors in the fast path.
+
+
+How to build the suite?
+-----------------------
+  The build instruction of DPDK suite should be followed and that would build
+  ENIC PMD library as well.
+
+  Typically, a user would execute the following commands to build the suite
+   - tar -xzf dpdk-<version>.tar.gz
+   - cd dpdk-<version>
+   - make install T=x86_64-native-linuxapp-gcc
+
+
+Version Information
+-------------------
+  The version of ENIC driver will be printed by ENIC PMD during the 
+  intialization.
+
+  This release notes is a part of version number 1.0.0.3
+
+Directory Structure
+-------------------
+librte_pmd_enic
+|-- LICENSE
+|      License terms
+|
+|-- Makefile
+|      Makefile to build ENIC PMD as a part of building DPDK
+|
+|-- scripts

+|
+`-- src
+       Source code of ENIC PMD
+
+
+Dependencies
+------------
+ - If the user wants to use DPDK with VFIO, the Linux kernel used 
+   should have support for Linux VFIO.  Linux kernels post 3.6.0 supports VFIO
+
+   The header file vfio.h should be present in /usr/include/linux/
+
+   For kernels post 3.6.0, this file should be present in 
+   <kernel_src_dir>/usr/include/linux/
+
+   In the case of Ubuntu, if the file is not present, install the 
+   package linux_libc_dev
+
+ - This version of ENIC PMD has been tested with DPDK suite version 1.7.1
+
+ - For using UIO framework, please refer the documentation that comes with
+   DPDK suite
+
+
+Supported Cisco VIC adapters 
+----------------------------
+ - ENIC PMD could be used with all the generations of Cisco VIC adapters.
+ - Flow director feature is not supported on generation 1 Cisco VIC adapters
+   (M81KR and P81E)
+
+
+Supported Operating Systems
+---------------------------
+Any Linux distribution fulfilling the conditions described in Dependencies 
+section of this document.
+
+Supported features in this release
+------------------------------------
+ - Unicast, multicast and broadcast transmission and reception
+ - Receive queue polling
+ - Statistics
+ - Hardware VLAN acceleration
+ - IP checksum offload
+ - Receive side header-split
+ - Receive side VLAN stripping
+ - Multiple receive and transmit queues
+ - Perfect filters for flow direction (supported on all adapters except M81KR
+   and P81E)
+ - Promiscuous mode
+ - Setting RX VLAN (supported via UCSM/CIMC only)
+ - VLAN filtering (supported via UCSM/CIMC only)
+ - Execution of application by unprivileged system users
+ 
+
+Known bugs and Unsupported features in this release
+---------------------------------------------------
+ - Signature filters
+ - Drop feature of perfect filters
+ - VLAN based flow direction
+ - Flexbytes based flow direction
+ - Setting of extended VLAN
+
+
+Prerequisites
+-------------
+ - Prepare the system as recommended by DPDK suite.  This includes environment
+   variables, hugepages configuration, tool-chains and configuration
+ - Insert vfio-pci kernel module using the command 'modprobe vfio-pci' if the
+   user wants to use VFIO framework
+ - Insert uio kernel module using the command 'modprobe uio' if the user wants
+   to use UIO framework
+ - DPDK suite should be configured based on the user's decision to use VFIO or
+   UIO framework
+ - Bind the intended vNIC to vfio-pci using librte_pmd_enic/scripts/bind_to_vfio
+   in case the user wants ENIC PMD to use VFIO framework
+ - Bind the intended vNIC to igb_uio in case the user wants ENIC PMD to use
+   UIO framework
+
+ Now, the system is ready to run the application.  Once the application runs to 
+ completion, if it is required, the vNIC could be detached from vfio-pci or igb_uio.
+ vNICs could be detached from vfio-pci using the script
+ librte_pmd_enic/scripts/unbind_from_vfio
+
+ Root privilege is required to bind and unbind vNICs to/from VFIO/UIO.
+
+ VFIO framework helps an unprivileged user to run the applications.
+
+ For an unprivileged user to run the applications on DPDK and ENIC PMD,
+ it might be required to increase the maximum locked memory of the user.
+ The following command could be used to do this.
+
+ sudo sh -c "ulimit -l <value in Kilo Bytes>"
+
+ The value depends on the memory configuration of the application, DPDK and
+ PMD.  Typically, the limit has to be raised to higher than 2GB. 
+ e.g., 2621440
+
+ The compilation of any unused drivers could be turned off using the
+ configuration file in config/ directory (e.g., config/common_linuxapp).  
+ This would help in bringing down the time taken for building the 
+ libraries and the initialization time of the application.

Thomas,

This patch is based on 1.7.1.  Thought that is the latest.  And I got the
diff from origin.
What made you feel that the patch is from 1.7?

Regards,

Neil,

If I move the DPDK patch that accommodates ENIC PMD (that is the one that
patches lib/Makefile) to the last in the series, builds between commits
would succeed, wouldn¹t it?  Moving that to the last is anyway needed.

Thanks,

Thomas,
These are files common to all flavours (user-space as well as kernel mode)
of VIC drivers.  I shall add this info to the commit logs.
Let me rework the directory structure too.

Thanks,
