|
| 20 | * @func_inst: USB function instance.
|
| 21 | * @net: The net_device associated with the EEM function.
|
| 22 | * @bound: True if the net_device is shared and pre-registered during the
|
| 23 | * legacy composite driver's bind phase (e.g., multi.c). If false,
|
| 24 | * the EEM function will register the net_device during its own
|
| 25 | * bind phase.
|
| 26 | * @bind_count: Tracks the number of configurations the EEM function is
|
| 27 | * bound to, preventing double-registration of the @net device.
|
| 28 | * @lock: Protects the data from concurrent access by configfs read/write
|
| 29 | * and create symlink/remove symlink operations.
|
| 30 | * @refcnt: Reference counter for the function instance.
