This is initial work of new simplified TAP device that uses the Linux kernel ioring API to provide a read/write ring with kernel.
This is split from tap device because there are so many unnecessary things in existing tap, and supporting ioring is better without ifdefs etc. The default name of the tap device is different that other uses in DPDK but the driver tries to keep the same relevant devargs as before. This driver will only provide features that match what kernel does, so no flow support etc. The next version will add checksum and multi-segment packets. Some of the doc files may need update as well.
