From 9d396fc1e8a7068acaa34eef2f87409c16a209bd Mon Sep 17 00:00:00 2001 From: Birger Koblitz Date: Tue, 18 Jan 2022 20:53:31 +0100 Subject: realtek: Add L2 aging configuration functions for all SoC families Instead of a generic L2 aging configuration function with complex logic, we implement an individual function for all SoC types.
