  10  * relationship of job descriptors to shared descriptors (SteveC Dec 10 2008):

  13  * | JobDesc #1  |-------------------->|  ShareDesc  |
  14  * | *(packet 1) |                     |   (PDB)     |
  15  * ---------------      |------------->|  (hashKey)  |
  16  *       .              |              | (cipherKey) |
  17  *       .              |    |-------->| (operation) |
  18  * ---------------      |    |         ---------------
  19  * | JobDesc #2  |------|    |
  20  * | *(packet 2) |           |
  21  * ---------------           |
  22  *       .                   |
  23  *       .                   |
  24  * ---------------           |
  25  * | JobDesc #3  |------------
  26  * | *(packet 3) |
  27  * ---------------
  28  *
  29  * The SharedDesc never changes for a connection unless rekeyed, but
  30  * each packet will likely be in a different place. So all we need
  31  * to know to process the packet is where the input is, where the
  32  * output goes, and what context we want to process with. Context is
  33  * in the SharedDesc, packet references in the JobDesc.
  34  *
  35  * So, a job desc looks like:
  36  *
  37  * ---------------------
  38  * | Header            |
  39  * | ShareDesc Pointer |
  40  * | SEQ_OUT_PTR       |
  41  * | (output buffer)   |
  42  * | (output length)   |
  43  * | SEQ_IN_PTR        |
  44  * | (input buffer)    |
  45  * | (input length)    |
  46  * ---------------------
