+Checksum:
+
+ * CRC32
+ * ADLER32
+
+To enable a checksum in the driver, the compression and/or decompression xform
+structure, rte_comp_xform, must be filled with either of the CompressDev
+checksum flags supported. ::
+
+ compress_xform->compress.chksum = RTE_COMP_CHECKSUM_CRC32
+
+ decompress_xform->decompress.chksum = RTE_COMP_CHECKSUM_CRC32
+
+::
+
+ compress_xform->compress.chksum = RTE_COMP_CHECKSUM_ADLER32
+
+ decompress_xform->decompress.chksum = RTE_COMP_CHECKSUM_ADLER32
+
+If you request a checksum for compression or decompression,
+the checksum field in the operation structure, ``op->output_chksum``,
+will be filled with the checksum.
+
+.. Note::
+
+ For the compression case above, your output buffer will need to be large enough to hold the compressed data plus a scratchpad for the checksum at the end, the scratchpad is 8 bytes for CRC32 and 4 bytes for Adler32.
