 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.
-* Number of segments in mbuf chains in the op must be <= RTE_PMD_QAT_COMP_SGL_MAX_SEGMENTS from the config file.
-* When using Deflate dynamic huffman encoding for compression, the input size (op.src.length)
-  must be < CONFIG_RTE_PMD_QAT_COMP_IM_BUFFER_SIZE from the config file,
-  see :ref:`building_qat_config` for more details.
+* Stateful compression is not supported.
