Title:
  Adding/removing ports leaks memory in dpdk

Status in dpdk package in Ubuntu:
  Triaged
Status in dpdk source package in Xenial:
  Fix Committed

Bug description:
  I set up a nicely working OVS-DPDK with KVM Guests.
  Then in a loop I
     - add up to 512 ports
     - test connectivity
     - remove up to 512 ports

  The effective error is like the issues discussed upstream about >1023 file descriptors - OVS-DPDK crashes due to that.
  A lot in the log afterwards are just follow on issues.

  But the problem of this bug is that there has to be some sort of leak of file descriptors (or something else depending on analysis).
  Because one would expect that adding/removing the same amount of ports should not exceed any "more" of a limit than in the first iteration.

  Of 12 planned iterations in 2 of 2 tries I now always failed at iteration 6.
  So I hope it is rather reproducible and will start debugging it.
