+ * queue ring buffer where the calling function can write its packet. It is
+ * Guaranteed that there is enough space for that packet. It also updates the
+ * pending write pointer to that location so subsequent calls to
+ * acquire_packet_buffer will get a correct write pointer
+ *
+ * kq_submit_packet: Update the write pointer and doorbell of a kernel queue.
+ *
+ * kq_rollback_packet: This routine is called if we failed to build an acquired
+ * packet for some reason. It just overwrites the pending wptr with the current
+ * one
