I can do that, but I am not sure I understand the logic of this test to begin with: looking into other PMD (mlx4, i40e), it seems to be the only one worrying about updating link state only when "ready" for some not clear (to me) definition of "ready".
I'll tend to agree with other PMD here: if the syscalls did not failed we should just update with what we know.
Why was this test introduced and what did it fixed?
