====================
Two generic xdp related follow-ups

Two follow-ups for the generic XDP API, would be great if
both could still be considered, since the XDP API is not
frozen yet. For details please see individual patches.

v1 -> v2:
  - Implemented feedback from Jakub Kicinski (reusing
    attribute on dump), thanks!
  - Rest as is.
