Subject: bnx2x: Restore 1G LED on BCM57712+BCM8727 designs.
X-Git-Tag: upstream/snapshot3+hdmi~7744^2~20
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9379c9be4b20d5cb7bde577f402b749cd7d3caa2;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

bnx2x: Restore 1G LED on BCM57712+BCM8727 designs.

Fix no-LED problem when link speed is 1G on BCM57712 + BCM8727 designs, by
removing a logic error checking for a different PHY.
