[dpdk-dev] [PATCH 1/2] scripts: add checkpatch wrapper

[Thomas Monjalon]

This script can be used to call checkpatch.pl from Linux with some
custom DPDK options.

The path to the original Linux script must be set in an environment
variable. A script is added to load any configuration variables
required by development tools from a file .develconfig, or
~/.config/dpdk/devel.config or /etc/dpdk/devel.config.
