There are two different mechanisms to set to downshift. And i think
some of the older PHYs don't support it at all. How did you decide on
which method to use for each PHY?

When I said "For all supported PHYs" I mean PHYs whith set_phy_tunable
defined. So I just added appropriate call of set_downshift found at
m88*_set_tunable functions to config_init of each PHY with
set_phy_tunable defined.

Hi Maxim
Please expand the commit message. It does not explain enough, which is
why i asked the odd question. Maybe something like:
A number of PHYs support the PHY tunable to set and get
downshift. However, only 88E1116R enables downshift by default. Extend
this default enabled to all the PHYs that support the downshift
tunable.
Andrew
