ed to add a wrapper to the
individual packages to manage package dependecy. For example, to test ovs-dpdk vswitch solution,
the build of ovs would depend on the build result of dpdk.
This dependency is never explicitly specified in the individual package.
For the second goal as a CI tool, it may not be needed to pull the upstream package.
So this whole folder can be ignored.
### Files and subfolders
* package-list: contains list of packages and their associated tags
* mk: contains top level makefiles
* dpdk: place holder for dpdk package
* ovs: place holder for ovs package.
* l2fwd: simple l2 forwarding kernel module
