 * wlan_nlink_srv.h
 *
 * 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.
