Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
ice: Block switchdev mode when ADQ is active and vice versa<br />
<br />
ADQ and switchdev are not supported simultaneously. Enabling both at the<br />
same time can result in nullptr dereference.<br />
<br />
To prevent this, check if ADQ is active when changing devlink mode to<br />
switchdev mode, and check if switchdev is active when enabling ADQ.
