Subject: [PATCH net-next 0/3] net: phy: dp83822: Add support for changing
 the MAC series termination

The dp83822 provides the possibility to set the resistance value of the
the MAC series termination. Modifying the resistance to an appropriate
value can reduce signal reflections and therefore improve signal quality.
