Merge branch 'generic-xdp-followups'
Daniel Borkmann says:
====================
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.
====================
