Koen Vandeputte 7488be7010 uqmi: fix raw-ip mode for newer lte modems
Some newer LTE modems, like the MC7455 or EC25-E do not support
"802.3" mode, and will stay in "raw-ip" regardless of the mode being
set.

In this case, the driver must be informed that it should handle all
packets in raw mode. [1]

This commit fixes connectivity issues for these devices.

This is the buildsystem for the OpenWrt Linux distribution.

Please use "make menuconfig" to choose your preferred
configuration for the toolchain and firmware.

You need to have installed gcc, binutils, bzip2, flex, python, perl, make,
find, grep, diff, unzip, gawk, getopt, subversion, libz-dev and libc headers.

Run "./scripts/feeds update -a" to get all the latest package definitions
defined in feeds.conf / feeds.conf.default respectively
and "./scripts/feeds install -a" to install symlinks of all of them into
package/feeds/.

Use "make menuconfig" to configure your image.

Simply running "make" will build your firmware.
It will download all sources, build the cross-compile toolchain, 
the kernel and all choosen applications.

To build your own firmware you need to have access to a Linux, BSD or MacOSX system
(case-sensitive filesystem required). Cygwin will not be supported because of
the lack of case sensitiveness in the file system.
