While before the my_client_index variable was stored as global variable in api_main_t, after commit 2ca88ff97884ec9ed20a853b13cee6d86f9c9d0f the my_client_index becomes part of vapi_ctx_t. Each API client (internal/external) connected to VPP stores its client index in vapi_ctx_t. The issue is in the client disconnection. The vapi_disconnect is untouched in patch 2ca88ff97884ec9ed20a853b13cee6d86f9c9d0f, so it keeps the behavior of using the my_client_index stored in api_main_t. Ticket: VPP-2069 Type: fix Fixes: 2ca88ff97884ec9ed20a853b13cee6d86f9c9d0f Signed-off-by: Mauro Sardara <msardara@cisco.com> Change-Id: Idf8c1d1056cbd631cc3057cf7acc486216fa8303 (cherry picked from commit 8c626b41eaab5c74e7e023205f1c6cd655d40f44)
Vector Packet Processing
Introduction
The VPP platform is an extensible framework that provides out-of-the-box production quality switch/router functionality. It is the open source version of Cisco's Vector Packet Processing (VPP) technology: a high performance, packet-processing stack that can run on commodity CPUs.
The benefits of this implementation of VPP are its high performance, proven technology, its modularity and flexibility, and rich feature set.
For more information on VPP and its features please visit the FD.io website and What is VPP? pages.

Getting started
In general anyone interested in building, developing or running VPP should consult the VPP wiki for more complete documentation.
In particular, readers are recommended to take a look at [Pulling, Building, Running, Hacking, Pushing](https://wiki.fd.io/view/VPP/Pulling,_Building,_Run ning,_Hacking_and_Pushing_VPP_Code) which provides extensive step-by-step coverage of the topic.
For the impatient, some salient information is distilled below.
Quick-start: On an existing Linux host
To install system dependencies, build VPP and then install it, simply run the
build script. This should be performed a non-privileged user with sudo
access from the project base directory:
./extras/vagrant/build.sh
If you want a more fine-grained approach because you intend to do some
development work, the Makefile
in the root directory of the source tree
provides several convenience shortcuts as make
targets that may be of
interest. To see the available targets run:
make
Quick-start: Vagrant
The directory extras/vagrant
contains a VagrantFile
and supporting
scripts to bootstrap a working VPP inside a Vagrant-managed Virtual Machine.
This VM can then be used to test concepts with VPP or as a development
platform to extend VPP. Some obvious caveats apply when using a VM for VPP
since its performance will never match that of bare metal; if your work is
timing or performance sensitive, consider using bare metal in addition or
instead of the VM.
For this to work you will need a working installation of Vagrant. Instructions for this can be found [on the Setting up Vagrant wiki page] (https://wiki.fd.io/view/DEV/Setting_Up_Vagrant).
More information
Several modules provide documentation, see @subpage user_doc for more end-user-oriented information. Also see @subpage dev_doc for developer notes.
