I managed to get my hands on an old BCM97435SVMB board to do some testing with the latest kernel and uncovered a number of things that managed to get broken over the years (some by me ;).
This commit set attempts to correct the errors I observed in my testing. The first commit applies to all internal PHYs to restore proper reporting of link status when a link comes up. The second commit restores the soft reset to the initialization of the older internal EPHYs used by 40nm Set-Top Box devices. The third corrects a bug I introduced when removing excessive soft resets by altering the initialization sequence in a way that keeps the GENETv3 MAC interface happy. Finally, I observed a number of issues when manually configuring the network interface of the older EPHYs that appear to be resolved by the fourth commit.
