That is much to short a message for a critical fix.
How about this (AI generated) message. Can I add that during
merge?

Subject: [PATCH v2 01/12] net/r8169: fix crash in RTL8168FP init

The rtl8168fp_ops structure was missing the hw_phy_mcu_config
function pointer, causing a NULL pointer dereference during
device initialization when the driver attempts to configure
the PHY microcontroller.

Add hw_phy_mcu_config_8168fp() as a no-op function since the
RTL8168FP does not require PHY MCU configuration. This matches
the pattern used by other chip variants that don't need PHY
MCU updates.
