From 0b0062d36bc43d80eb8e9e6905cd991a85028a21 Mon Sep 17 00:00:00 2001 From: "Russell King (Oracle)" Date: Thu, 7 Apr 2022 15:52:22 +0100 Subject: net: mtk_eth_soc: partially convert to phylink_pcs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Partially convert mtk_eth_soc to phylink_pcs, moving the configuration, link up and AN restart over. However, it seems mac_pcs_get_state() doesn't actually get the state from the PCS, so we can't convert that over without a better understanding of the hardware.
