+* **Removed coalescing feature from Intel QuickAssist Technology (QAT) PMD.**
+
+  The internal tail write coalescing feature was removed as not compatible with
+  dual-thread feature. It was replaced with a threshold feature. At busy times
+  if only a small number of packets can be enqueued, each enqueue causes
+  an expensive MMIO write. These MMIO write occurrences can be optimised by using
+  the new threshold parameter on process start. Please see qat documentation for
+  more details.
