openwrt/target/linux/bcm47xx/patches-5.15/791-tg3-no-pci-sleep.patch

When the Ethernet controller is powered down and someone wants to 
access the mdio bus like the witch driver (b53) the system crashed if 
PCI_D3hot was set before. This patch deactivates this power sawing mode 
when a switch driver is in use.
