Hi David,
	Checkpatch CI is showing "WARNING" on a lot of the patches in this series, but it does not list any real warnings.  Any idea what is happening?

Thanks,
Honnappa

> It is pretty common for the DPDK applications to be deployed in semi-
> pipeline model. In these models, a small number of cores (typically 1) are
> designated as I/O cores. The I/O cores work on receiving and transmitting
> packets from the NIC and several packet processing cores. The IO core and
> the packet processing cores exchange the packets over a ring. Typically, such
> applications receive the mbufs in a temporary array and copy the mbufs on
> to the ring. Depending on the requirements the packets could be copied in
> batches of 32, 64 etc resulting in 256B, 512B etc memory copy.

> The zero copy APIs help avoid intermediate copies by exposing the space on
> the ring directly to the application.
