Descriptors rewritten using RTA were tested to be bit-exact
(i.e. exact hex dump) with the ones being replaced, with
the following exceptions:
-shared descriptors - start index is 1 instead of 0; this has
no functional effect
-MDHA split keys are different - since the keys are the pre-computed
IPAD | OPAD HMAC keys encrypted with JDKEK (Job Descriptor
Key-Encryption Key); JDKEK changes at device POR.
