Thanks for mentioning the nit about reverse christmas tree order; I
missed that.

I will:
  - Fix the ordering of the variables in 1/2
  - Add 2 comments in 2/2

I'll have to wait the ~48hr timeout before I can post the v2, but
I'll be sure to CC you on the next revision.

No worries, thanks for the review.

BTW: Since neither of the changes you've asked me to make are
functional changes, would you mind testing the driver changes on
your side just to make sure? I tested them myself on an ec2 instance
with an ENA driver, but I am not an expert on ENA :)
