Subject: [PATCH net-next 0/1 v3] drivers: net: Add support for rmnet driver

This patch adds support for the rmnet_data driver which is required to
support recent chipsets using Qualcomm Technologies, Inc. modems. The data
from hardware follows the multiplexing and aggregation protocol (MAP).

This driver can be used to register onto any physical network device in
IP mode. Physical transports include USB, HSIC, PCIe and IP accelerator.

rmnet_data driver helps to decode these packets and queue them to network
stack (and encode and transmit it to the physical device).

--
v1: Same as the RFC patch with some minor fixes for issues reported by
kbuild test robot.

v1->v2: Change datatypes and remove config IOCTL as mentioned by David.
Also fix checkpatch issues and remove some unused code.

v2->v3: Move location to drivers/net and rename to rmnet. Change the
userspace - netlink communication from custom netlink to rtnl_link_ops.
Refactor some code. Use a fixed config for ingress and egress.
