Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: dsa: b53: do not enable EEE on bcm63xx<br /> <br /> BCM63xx internal switches do not support EEE, but provide multiple RGMII<br /> ports where external PHYs may be connected. If one of these PHYs are EEE<br /> capable, we may try to enable EEE for the MACs, which then hangs the<br /> system on access of the (non-existent) EEE registers.<br /> <br /> Fix this by checking if the switch actually supports EEE before<br /> attempting to configure it.
