Hello: This patch was applied to netdev/net.git (main) by Jakub Kicinski [off-list ref]: On Wed, 18 Feb 2026 05:28:22 +0000 you wrote:
The LAN7801 is designed exclusively for external PHYs (unlike the LAN7800/LAN7850 which have internal PHYs), but lan78xx_mdio_init() restricts PHY scanning to MDIO addresses 0-7 by setting phy_mask to ~(0xFF). This prevents discovery of external PHYs wired to addresses outside that range. One such case is the DP83TC814 100BASE-T1 PHY, which is typically configured at MDIO address 10 via PHYAD bootstrap pins and goes undetected with the current mask. [...]
