[PATCH net-next] net: sfp: add quirk for TP-LINK SM410U
From: Daniel Golle
Date: Sat Oct 10 2026 - 20:52:09 EST
The TP-LINK SM410U is a 2.5G copper module which is based on RealTek
RTL8221B, but doesn't seem to offer any way to access the PHY over I2C.
Add a quirk to disable in-band which isn't supported by the PHY.
