Summary: Vector Packet Processing
License: MIT
Version: %{_version}
Release: %{_release}
Requires: vpp-lib = %{_version}-%{_release}, net-tools, pciutils, python
BuildRequires: systemd

%description
This package provides VPP executables: vpp, vpp_api_test, vpp_json_test
vpp - the vector packet engine
vpp_api_test - vector packet engine API test tool
vpp_json_test - vector packet engine JSON test tool

%package lib
Summary: VPP libraries
Group: System Environment/Libraries

%description lib
This package contains the VPP shared libraries, including:
vppinfra - foundation library supporting vectors, hashes, bitmaps, pools, and string formatting.
dpdk - Intel DPDK library
svm - vm library
vlib - vector processing library
vlib-api - binary API library
vnet -  network stack library

%package devel
Summary: VPP header files, static libraries
Group: Development/Libraries
Requires: vpp-lib

%description devel
This package contains the header files and static libraries for
vppinfra.  Install this package if you want to write or compile a
program that needs vpp.
Do we need to list those header files or just leave it blank ? 
dynamic vectors (vec.c), dynamic bitmaps (bitmap.h), allocation heap of
objects (heap.c), allocation pool(pool.h), dynamic hash tables (hash.c), memory
allocator (mheap.c), extendable printf-like interface built on top of vectors
(format.c), formats for data structures (std-formats.c), and support for clock
time-based function calls (timer.c).
TODO: reference and describe only the .h files
