+AD4 This patch increases max+AF8-sgl+AF8-segments value to max supported
+AD4 which is 1024. Increase in max+AF8-sgl+AF8-segments will support larger
+AD4 IO size from driver.

Where does the original value +ACI-128+ACI come from? Where does the new value +ACI-1024+ACI
come from? Do all firmware versions support the new and larger value?

Thanks,
