openwrt/target/linux/bcm27xx/patches-6.6/950-0127-lan78xx-Move-enabling-of-EEE-into-PHY-init-code.patch
Álvaro Fernández Rojas 8c405cdccc bcm27xx: add 6.6 kernel patches
The patches were generated from the RPi repo with the following command:
git format-patch v6.6.34..rpi-6.1.y

Some patches needed rebasing and, as usual, the applied and reverted, wireless
drivers, Github workflows, READMEs and defconfigs patches were removed.

Subject: [PATCH 0127/1085] lan78xx: Move enabling of EEE into PHY init code
Enable EEE mode as soon as possible after connecting to the PHY, and
before phy_start. This avoids a second link negotiation, which speeds
up booting and stops the interface failing to become ready.
