The main changes are:

   that 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,
