| 30 | * |
| 31 | * wlan_nlink_srv is used to RX/TX Netlink messages from user space to kernel |
| 32 | * modules and vice versa. Kernel modules must register a message handler for a |
| 33 | * message type so that the wlan_nlink_srv can invoke the corresponding msg handler |
| 34 | * whenever a Netlink message of a particular type has been received from an |
| 35 | * application. In the opposite direction, wlan_nlink_srv provides a mechanism |
| 36 | * which kernel modules can use to send Netlink messages to applications. |
