Upstream change submitted to fix this.

** Changed in: linux-hwe-edge (Ubuntu)
       Status: Invalid => In Progress

** Changed in: linux-hwe-edge (Ubuntu Bionic)
       Status: Invalid => In Progress

** Description changed:

+ [Impact]
+ selftests will incorrectly indicate a failure, taking the time of developers 
to verify a false positive, and preventing us from finding real bugs in the 
corresponding code.
+ 
+ [Test case]
+ Run the script directly and verify there are no failures.
+ sudo ./tools/testing/selftests/net/pmtu.sh
+ 
+ [Regression potential]
+ No kernel code was changed, only the test. The fix could cause false 
positives to happen with newer versions of iproute2, but those were tested as 
well.
