nrf_wifi_fmac_start_xmit()

enum nrf_wifi_status nrf_wifi_fmac_start_xmit	(	void *	fmac_dev_ctx,
		unsigned char	if_idx,
		void *	netbuf )

Transmit a frame to the RPU.

Parameters

fmac_dev_ctx	Pointer to the UMAC IF context for a RPU WLAN device.
if_idx	Index of the interface on which the frame is to be transmitted.
netbuf	Pointer to the OS specific network buffer.

This function takes care of transmitting a frame to the RPU firmware. It does the following:

   - Queues the frames to a transmit queue.
   - Based on token availability, sends one or more frames to the RPU using
     the command for transmission.
   - The firmware sends an event once the command has
     been processed to indicate whether the frame(s) have been
     transmitted/aborted.
   - The driver can cleanup the frame buffers after receiving this event.

Return values

NRF_WIFI_STATUS_SUCCESS	On success
NRF_WIFI_STATUS_FAIL	On failure to execute command
