+ * The SharedDesc never changes for a connection unless rekeyed, but

+ * in the SharedDesc, packet references in the JobDesc.
+ *
+ * So, a job desc looks like:

+ * ---------------------
+ * | Header            |
+ * | ShareDesc Pointer |
+ * | SEQ_OUT_PTR       |
+ * | (output buffer)   |
+ * | (output length)   |
+ * | SEQ_IN_PTR        |
+ * | (input buffer)    |
+ * | (input length)    |
