MFC 323170

  if: Add ioctls to get RSS key and hash type/function.

  It will be needed by hn(4) to configure its RSS key and hash
  type/function in the transparent VF mode in order to match VF's
  RSS settings. The description of the transparent VF mode and
  the RSS hash value issue are here:

  These are generic enough to promise two independent IOCs instead
  of abusing SIOCGDRVSPEC.

  Setting RSS key and hash type/function is a different story,
  which probably requires more discussion.

  Comment about UDP_{IPV4,IPV6,IPV6_EX} were only in the patch
  in the review request; these hash types are standardized now.
