This has a history, same patch has been done in the past by Andrew [1], later 
reverted [2] (by me) since some PMDs failed and we were close to release.

In recent discussion [3] already agreed to get the patch again before -rc1, and 
this time there will be time to fix failing PMDs.
Thanks for making the patch.


[1] Commit bdca79053b6a ("app/testpmd: set fixed flag for exact link speed")
