37Description:
38 Shows if the mode is active or not. The attribute can be used
39 for entering/exiting the mode with partners and cable plugs, and
40 with the port alternate modes it can be used for disabling
41 support for specific alternate modes. Entering/exiting modes is
42 supported as synchronous operation so write(2) to the attribute
43 does not return until the enter/exit mode operation has
44 finished. The attribute is notified when the mode is
45 entered/exited so poll(2) on the attribute wakes up.
46 Entering/exiting a mode will also generate uevent KOBJ_CHANGE.
