| 37 | Description: | |
| 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. | |
