* **Added support of dynamic fields and flags in mbuf.**
* **Added support for dynamic fields and flags in mbuf.**
This new feature adds the ability to dynamically register some room
for a field or a flag in the mbuf structure. This is typically used
for specific offload features, where adding a static field or flag
in the mbuf is not justified.
* **Added hairpin queue.**
* **Added support for hairpin queues.**
On supported NICs, we can now setup haipin queue which will offload packets
from the wire, backto the wire.
