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.
