Title:
  ip_defrag.sh in net from ubuntu_kernel_selftests failed with exit code
  255 on F-oem-5.6

Status in ubuntu-kernel-tests:
  Fix Released
Status in linux-oem-5.6 package in Ubuntu:
  Invalid
Status in linux-oem-5.6 source package in Focal:
  Fix Released

Bug description:
  [Impact]
  The ip_defrag.sh test in net from kernel-selftest failed with exit
  code 255:
   # selftests: net: ip_defrag.sh
   not ok 18 selftests: net: ip_defrag.sh # exit=255

  [Fix]
  * aba69d49fb49c9 ("selftests: net: ip_defrag: modprobe missing
  nf_defrag_ipv6 support")

  This patch can be cherry-picked into OEM-5.6

  [Test Case]
  Run this script after building the net test in kselftest directory
  (linux/tools/testing/selftests) from the kernel tree:
   make TARGETS=net
   cd net
   sudo ./ip_defrag.sh

  With this patch applied the test will pass without any issue.

  [Where problems could occur]
  Change limited to the test case only. And this has already included
  in other kernels, it's unlikely to cause problems.

  [Original Bug Report]
  Issue found on 5.6.0-1050.54 - oem

  The ip_defrag.sh test failed with:
   # selftests: net: ip_defrag.sh
   not ok 18 selftests: net: ip_defrag.sh # exit=255

  I don't think this can be called as a regression, since the
  ubuntu_kernel_selftests test was removed and added back to the test
  suite until the most recent cycle. And this issue can be reproduced
  with 5.6.0-1048-oem as well.

  Note that we have another issue for this test filed against F-oem-5.6 in 
before, see bug 1908498
  It looks like there are several changes after this test since then.
