/**
+ * Decide which checksums both client and OST support, possibly forcing
+ * the use of T10PI checksums if the hardware supports this.
+ *
+ * The clients that have no T10-PI RPC checksum support will use the same
+ * mechanism to select checksum type as before, and will not be affected by
+ * the following logic.
+ *
+ * For the clients that have T10-PI RPC checksum support:
+ *
+ * If the OST supports T10-PI feature and T10-PI checksum is enforced, clients
+ * will have no other choice for RPC checksum type other than using the T10PI
+ * checksum type. This is useful for enforcing end-to-end integrity in the
+ * whole system.
+ *
+ * If the OST doesn't support T10-PI feature and T10-PI checksum is enforced,
+ * together with other checksum with reasonably good speeds (e.g. crc32,
+ * crc32c, adler, etc.), all T10-PI checksum types understood by the client
+ * (t10ip512, t10ip4K, t10crc512, t10crc4K) will be added to the available
+ * checksum types, regardless of the speeds of T10-PI checksums. This is
+ * useful for testing T10-PI checksum of RPC.
+ *
+ * If the OST supports T10-PI feature and T10-PI checksum is NOT enforced,
+ * the corresponding T10-PI checksum type will be added to the checksum type
+ * list, regardless of the speed of the T10-PI checksum. This provides clients
+ * the flexibility to choose whether to enable end-to-end integrity or not.
+ *
+ * If the OST does NOT supports T10-PI feature and T10-PI checksum is NOT
+ * enforced, together with other checksums with reasonably good speeds,
+ * all the T10-PI checksum types with good speeds will be added into the
+ * checksum type list. Note that a T10-PI checksum type with a speed worse
+ * than half of Alder will NOT be added as a option. In this circumstance,
+ * T10-PI checksum types has the same behavior like other normal checksum
+ * types.
