This patch series adds a dynamic port hotplug framework to DPDK.

Currently, dpdk has no ability to know which type of driver(

Too many things are included in the programmers guide.
I think it should cover only API and knowledge needed to make an application.
That's why I suggest to move Xen and NICs doc outside.
Then it will be easier to add doc for a new environment or a new NIC.
