[Fix]
* 3503ee6c0bec5f ("selftests: fix the return value for UDP GRO test")

We have this test since Focal.
This patch can be cherry-picked into all the affected kernels.

[Test]
Run this test with:
  sudo ./udpgro.sh

And check its final return value with:
  echo $?

If there is any failure, the return value should not be 0.

[Where problems could occur]
If this fix is incorrect it might affect the test execution, but it
should be fine as this is just affecting the test tool. Also, with
this patch, we are expecting to see this test case to fail until
bug 1908501 got fixed.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-groovy' to 'verification-done-groovy'. If the problem still exists, change the tag 'verification-needed-groovy' to 'verification-failed-groovy'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.
