Subject: [PATCH 0/2] net: usb: qmi_wwan: add qmap mux protocol support

This patch adds support for qmap mux protocol available in recent
Qualcomm based modems.

The qmap mux protocol can be used for multiplexing data packets in
order to have multiple ip streams through the same physical device.

Two new sysfs files are added for adding/removing the qmap mux based
interfaces (named qmimux):

/sys/class/net/<iface>/qmi/add_mux
/sys/class/net/<iface>/qmi/del_mux

Main patch author is Bjørn Mork <bjorn@...k.no>

An userspace implementation of the qmi requests needed to support
multiple ip streams is already available (namely libqmi since
version 1.18.0).

The qmap mux feature has been recently implemented in Codeaurora
gobinet out-of-kernel driver that was the inspiration for this
development.

Tests have been performed with Telit LE922A6 (PID 0x1040)
