Title:
  fib_nexthop_multiprefix.sh from net in ubuntu_kernel_selftests failed
  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 incorrect cleanup() in fib_nexthop_multiprefix.sh will cause failure
  to this script even if the test itself has passed.

  $ sudo ./fib_nexthop_multiprefix.sh
  TEST: IPv4: host 0 to host 1, mtu 1300                              [ OK ]

  TEST: IPv4: host 0 to host 3, mtu 1400                              [ OK ]
  TEST: IPv6: host 0 to host 3, mtu 1400                              [ OK ]
  $ echo $?
  1

  [Fix]
  * 651149f6037675 ("selftests: fib_nexthop_multiprefix: fix cleanup() netns
  deletion")

  This has already been applied to all the other generic kernels via stable
  update (bug 1891063)

  [Test case]
  Run this script and the return value will be 0

  [Where problems could occur]
  As it's just fixing the cleanup to make it match with setup(), it's
  unlikely to see bad things to happen here.
