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