To send an ethernet frame to WHD (called by the Network Stack)
This function takes ethernet data from the network stack and queues it for transmission over the wireless network. The function can be called from any thread context as it is thread safe, however it must not be called from interrupt context since it might get blocked while waiting for a lock on the transmit queue.
This function returns immediately after the packet has been queued for transmit, NOT after it has been transmitted. Packet buffers passed to the WHD are released inside the WHD once they have been transmitted.
| ifp | Pointer to handle instance of whd interface |
| buffer | Handle of the packet buffer to be sent. |
