Shared memory ring patch This patch enables the client dpdk rings within the netdev-dpdk. It adds a new dpdk device called dpdkr (other naming suggestions?). This allows for the use of shared memory to communicate with other dpdk applications, on the host or within a virtual machine. Instructions for use are in INSTALL.DPDK. This has been tested on Intel multi-core platforms and with the client application within the host.
