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

From: Dimitri Fedrau via B4 Relay
Date: Fri Mar 07 2025 - 05:31:32 EST


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.
