Subject: [PATCH net 0/4] net: bcmgenet: restore internal EPHY support

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.

Doug Berger (4):
  net: bcmgenet: don't set phydev->link from MAC
  net: phy: bcm7xxx: define soft_reset for 40nm EPHY
  net: bcmgenet: soft reset 40nm EPHYs before MAC init
  net: bcmgenet: reset 40nm EPHY on energy detect
