Subject: [PATCH net-next 10/15] net: stmmac: qcom-ethqos: move RGMII_CONFIG2_RX_PROG_SWAP
Date: Tue, 24 Mar 2026 13:12:20 +0000 [thread overview]
Message-ID: <E1w51YS-0000000DwWA-2Ob1@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <acKNcX5PqtWYf8m3@shell.armlinux.org.uk>
Move RGMII_CONFIG2_RX_PROG_SWAP out of the switch. 1G speed always
sets this field. 100M and 10M sets it for has_emac_ge_3 devices,
otherwise it is cleared.
