Added: trunk/target/linux/brcm47xx/patches-3.10/791-tg3-no-pci-sleep.patch trunk/target/linux/brcm47xx/patches-3.14/791-tg3-no-pci-sleep.patch Log: brcm47xx: fix bcm4705 rebooting when initializing the switch. 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.
