patch 'net/r8169: fix crash in RTL8168FP init' has been queued to stable release 25.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 25.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/02/26. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/66eb0cd0de02c7bcca11c0903296ac576c3505c2

Thanks.

Kevin

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

[ upstream commit 5887ff7505a4d599b2e971f42962156f2123a158 ]

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.

Fixes: d9ee71b5f1bc ("net/r8169: support RTL8168 series")
