Subject: [PATCH net] net: dsa: mv88e6xxx: drop adjust_link to enabled phylink

We have to drop the adjust_link callback in order to finally migrate to
phylink.

Otherwise we get the following warning during startup:
"mv88e6xxx 2188000.ethernet-1:10: Using legacy PHYLIB callbacks. Please
migrate to PHYLINK!"

The warning is generated in the function dsa_port_link_register_of in
dsa/port.c:

int dsa_port_link_register_of(struct dsa_port *dp)
{
struct dsa_switch *ds = dp->ds;

if (!ds->ops->adjust_link)
return dsa_port_phylink_register(dp);

dev_warn(ds->dev,
"Using legacy PHYLIB callbacks. Please migrate to PHYLINK!\n");
[...]
}

Hi Hubert

Do we need the same patch for the b53 driver?

Hi Andrew,

It looks like some work is still needed in b53_phylink_mac_config to
take over the
functionality of the current adjust_link implementation.

Indeed, I will look into it in the next few weeks.
