   is, keep resolving such instances instead of bailing out, from Lorenz Bauer.

2) Fix BPF test framework with regards to xdp_frame info misplacement in the
   "live packet" code, from Alexander Lobakin.

3) Fix an infinite loop in BPF sockmap code for TCP/UDP/AF_UNIX, from Liu Jian.

   doc links, from Bagas Sanjaya.
