Greg Suarez	9bf211a30b	net: cdc_mbim: adding MBIM driver ... The CDC Mobile Broadband Interface Model (MBIM) specification extends CDC NCM by - removing the redundant ethernet header from the point-to-point USB channel - adding support for multiple IP (v4 and/or v6) sessions multiplexed on the same USB channel - adding a MBIM control channel encapsulated in CDC - adding Device Service Streams (DSS), which are non IP generic data streams multiplexed on the same USB channel as the IP sessions MBIM devices are managed using the dedicated control channel, and no data will flow on the data channel until a control session has been established. This driver has no knowledge of MBIM control messages. It just exports the control channel to a /dev/cdc-wdmX character device for userspace management applications. Such an application is therefore required to use this driver. This patch implements basic MBIM support, reusing the NCM and WDM driver APIs, currently limited to IP sessions with SessionID 0. DSS and multiplexed IP sessions are not yet supported. Signed-off-by: Greg Suarez <gsuarez@smithmicro.com> Signed-off-by: Bjørn Mork <bjorn@mork.no> Signed-off-by: David S.
