    net/intel: optimize for fast-free hint
    
    When the fast-free hint is provided to the driver we know that the mbufs
    have refcnt of 1 and are from the same mempool. Therefore, we can
    optimize a bit for this case by:
    
    * resetting the necessary mbuf fields, ie. nb_seg and next pointer when
      we are accessing the mbuf on writing the descriptor.
    * on cleanup of buffers after transmit, we can just write those buffers
      straight to the mempool without accessing them.
    * when doing buffer cleanup, we can follow the model of the vector
      driver where we cleanup in fixed bursts which don't wrap, and where we
      track the mbufs between tx_tail and last_cleaned as invalid, so we
      don't need to set them to NULL. [We only set to NULL valid mbuf slots
      where we have a context descriptor or segment not backed by an mbuf]
