I agree as the train has left, but this got me thinking about these
questions that I hope Qlogic folks could answer:

 - Mention what else is different - perhaps there are other entries that
   are a bit different? Or maybe the are some non-standard ones added on?

 - How has this been tested? As in had all the fields been tested (so CHAP
   on/off, extra ports, etc).

 - Do future hardware of these cards use the standard one? If so what are they?
   "Anything produced in 2012 and later.." ?
 - Is the subset of hardware that use the non-standard small enough? Would it
   be good to mention it in the commit.

Thanks!
