Subject: [PATCH net-next 09/10] net: stmmac: qcom-ethqos: move SerDes speed configuration
Date: Mon, 23 Feb 2026 09:34:56 +0000 [thread overview]
Message-ID: <E1vuSLA-0000000AScc-3RFf@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <aZwfAFJQcp9f0niI@shell.armlinux.org.uk>
Move the SerDes speed configuration to phylink's .mac_finish() stage
so that the SerDes is appropriately configured for the interface mode
prior to the link coming up.
