Currently, if skb is non-linear, due to MHI skb chaining, it is linearized in MBIM RX handler prior MBIM decoding, causing extra allocation and copy that can be as large as the maximum MBIM frame size (32K). This change introduces MBIM decoding for non-linear skb, allowing to process 'large' non-linear MBIM packets without skb linearization. The IP packets are simply extracted from the MBIM frame using the skb_copy_bits helper. Signed-off-by: Loic Poulain <loic.poulain@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>
