Title:
  reuseport_bpf_numa in net from ubuntu_kernel_selftests failed on i386

Status in ubuntu-kernel-tests:
  Fix Released
Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Bionic:
  Fix Released

Bug description:
  == SRU Justification ==
  The reuseport_bpf_numa test in net category from ubuntu_kernel_selftests
  will fail on i386 systems with:
    selftests: reuseport_bpf_numa
    ========================================
    not ok 1..3 selftests: reuseport_bpf_numa [FAIL]

  If you run it directly, you will see the test is simply not supported.
    $ sudo ./reuseport_bpf_numa
    ./reuseport_bpf_numa: no numa api support: Function not implemented

  == Fix ==
  * 1a2b80ec (selftests: net: reuseport_bpf_numa: don't fail if no numa
   support)

  We have this patch in newer kernel from D, and we don't run this test
  on Xenial so only Bionic needs this patch.

  == Test ==
  Tested on a Bionic i386 node and it works as expected.
    selftests: reuseport_bpf_numa
    ========================================
    1..0 # Skipped: no numa api support
    ok 1..3 selftests: reuseport_bpf_numa [PASS]

  == Regression Potential ==
  Low, trival change to testing tool itself.

  
  == Original Bug Report ==
  Test failed with:
      $ sudo ./reuseport_bpf_numa
      ./reuseport_bpf_numa: no numa api support: Function not implemented

  Maybe this one should be skipped.

  selftests: reuseport_bpf_numa
   ========================================
   not ok 1..3 selftests: reuseport_bpf_numa [FAIL]
