[ Upstream commit 2ff2c7e274392871bfdee00ff2adbb8ebae5d240 ]
The test was setting the headroom size of the wrong port. This was not visible because of a firmware bug that canceled this bug.
Set the headroom size of the correct port, so that the test will pass with both old and new firmware versions.
