Hi Daniele / Bjørn
Is it possible to define a pass through mode in qmi_wwan. This is to
ensure that all packets in MAP format are passed through instead of
processing in qmi_wwan layer. The pass through mode would just call
netif_receive_skb() on all these packets.
That would allow all the packets to be intercepted by the rx_handler
attached by rmnet which would subsequently de-multiplex and process
the packets.
