+QAT compression PMD needs intermediate buffers to support Deflate compression
+with Dynamic Huffman encoding. CONFIG_RTE_PMD_QAT_COMP_IM_BUFFER_SIZE
+specifies the size of a single buffer, the PMD will allocate a multiple of these,
+plus some extra space for associated meta-data. For GEN2 devices, 20 buffers plus
+1472 bytes are allocated.
+
+.. Note::
+
+ If the compressed output of a Deflate operation using Dynamic Huffman
+ Encoding is too big to fit in an intermediate buffer, then the
+ operation will return RTE_COMP_OP_STATUS_ERROR and an error will be
+ displayed. Options for the application in this case
+ are to split the input data into smaller chunks and resubmit
+ in multiple operations or to configure QAT with
+ larger intermediate buffers.
