NetDev_MgmtDemux()

A device’s management demultiplex function is used to demultiplex a management frame to signal the Wireless Manager the response or to implement miscellaneous functionality such as updating the link state when the wireless network is out of the range and the connection is lost.

Prototype

          static  void  NetDev_MgmtDemux (NET_IF  *p_if,
                                          NET_BUF *p_buf,
                                          NET_ERR *p_err);

Note that since every device driver’s MgmtDemux() function is accessed only by function pointer via the device driver’s API structure, it doesn’t need to be globally available and should therefore be declared as ‘static’.

Arguments

p_if

Pointer to the interface to handle network device I/O operations.

p_buf

Pointer to the network buffer that contains the management frame.

p_err

Pointer to variable that will receive the return error code from this function.

Returned Value

None.

Required Configuration

None.

Notes / Warnings

When a management command has been sent and the Wireless Manager is waiting for the response, the Wireless Manager must be signaled by calling p_mgr_api->Signal().

The network buffer must be freed by the function if the Wireless Manager is not signaled and no error are returned by calling NetBuf_Free().
