This patchset adds functionality to the null driver help when testing a dataplane that uses dpdk. The idea is that the the dataplane can have multiple null interfaces attached, and each of theses can be assigned a mac address. Packets can then be injected into the null drivers by adding them to a ring, giving the application complete control of the packets that arrive. Packets that are sent by a null driver can be stored on a ring, where the application can pick them up and verify it is what was expected. To allow the application to know when packets have been pulled of the rx ring, counters of the number of times an rx poll has been made are kept, and these can be retrieved via the existing APIs.
All of these enhancements are using the existing APIs, and do not modify the existing behaviour of the null driver if these features are not configured.
