Subject: qed: Don't config min BW on 100g on link flap
X-Git-Tag: v4.7-rc2~20^2~23^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3e7cfce228c6c67dd31e09175eaca55fee0c7082;p=platform%2Fkernel%2Flinux-exynos.git

qed: Don't config min BW on 100g on link flap

Currently 100g devices don't support minimum/maximum BW configurations,
yet link flaps might cause the driver to attempt to do such a
configuration. Prevent this just as we do for the maximum BW.
