 Limitations
 -----------
 
 * Compressdev level 0, no compression, is not supported.
-* Queue pairs are not thread-safe (that is, within a single queue pair, RX and TX from different lcores is not supported).
+* Queue-pairs are thread-safe on Intel CPUs but Queues are not (that is, within a single
+  queue-pair all enqueues to the TX queue must be done from one thread and all dequeues
+  from the RX queue must be done from one thread, but enqueues and dequeues may be done
+  in different threads.)
 * No BSD support as BSD QAT kernel driver not available.
+* Stateful compression is not supported.
