Create net_l2_send() function which will be called by each L2 sending function so that we can catch all the network packets that are being sent. Some L2 layers send things a bit differently, so in those cases call the net_capture_send() directly by the L2 layer. Add network packet capture call in receive side after the pkt has been received by the RX queue handler. This avoids calling the net_capture_send() from ISR context.
