SKB tracking

The skb-tracking collector does not track itself skb in the kernel (this is done in the core) but allows to report the tracking information in the events. This tracking information, which is basically a unique "id", can be used at post-processing time to reconstruct in-kernel packets flow using the sort post-processing command.

Event

#{tracking id} (skb {skb address})

The tracking id is a unique id generated by Retis' tracking logic. The socket buffer address is also returned in the tracking events to help distinguish between clones (as they share the same tracking id).
