Awesome. Thank you Talat. This was actually a simple example I was giving
to Kamal, explaining to him how the SRU process worked and giving him a
real example on how to provide a debdiff and create a PPA. So, I really did
not expect the fix to be "good" but to give him so clue how things worked.

It is good that you are catching up with bugs. I'll compile the testcase,
backport the commits you are mentioning and provide you a PPA to test, okay
? Please expect this to take sometime (a week) because of my Ubuntu
Advantage workload.

Thank you !!

Cheers

Rafael

Title:
  nl_cache_refill; rtnl_neigh_get fail to find neighbors in cache

Status in libnl3 package in Ubuntu:
  In Progress

Bug description:
  Retrieving information about configured neighbors fail 
  my application is running the following procedure:

  neigh = NULL;
  cache = rtnl_neigh_alloc_cache(sk);
  while(NULL == neigh){
      nl_cache_refill(sk, chache);
      neigh = rtnl_neigh_get(cache, ifindex, dst_addr);
  }

  with libnl3 3.2.21-1 this loop will never end, even when adding a static arp entry.
  However, with libnl-3.2.24 the neighbor lookup succeed.
