In many cases, it's enough to simply let the application know that the call to initialize DPDK has failed. A complete halt can then be decided by the application based on error returned (and the app could even attempt a possible re-attempt after some corrective action by the user or application).
There is still some work left in this series. One bit of work left is to take the calls which could reasonably be corrected (and then init can be re-attempted), and make sure to clear the already-initialized flag. Another piece of work is to fix the lcore master/slave errors to properly reflect thread state. Finally, some real heavy testing should be done. The series wasn't tested much, and could use real soak time. Especially around some of the calls where it no longer returns an error (for instance, vdev init and plugin init).
