The DPDK needs to stay up to date with current LTS Linux kernel support.
If the kernel is older than LTS it is likely to be insecure and buggy.
Therefore only require DPDK to work on oldest LTS kernel.
If distribution vendors want to support DPDK on older kernels, that is
their choice. But the upstream source does not need to be cluttered
with support for this.

This updates mlx4 documentation and DPDK release notes
to reflect the PMD support for rdma-core from linux-rdma.
- PMD is now freed from Mellanox OFED and now only depends on the
public rdma-core package (v15 and above) instead.
(see https://github.com/linux-rdma/rdma-core/releases)
This PMD should run under Linux v4.14 and above.
- In case any of the above requirements can't be satisfied,
Mellanox OFED v4.2 and above also provide an updated rdma-core
as well back-ported kernel modules for most Linux distributions
and previous Linux versions.
(see http://www.mellanox.com/page/products_dyn?product_family=26).

This is a wrapper to Linux kernel get_maintainer.pl file and only
supports parsing MAINTAINERS file (no git fallback etc..)
Requires DPDK_GETMAINTAINER_PATH devel config option set, please check
devtools/load-devel-config.
DPDK_GETMAINTAINER_PATH should be full path to the get_maintainer.pl
script, like:
DPDK_GETMAINTAINER_PATH=~/linux/scripts/get_maintainer.pl
Can be used individually:
./devtools/get-maintainer.sh <my.patch>
Or via git send-email, to add maintainers automatically:
git send-email --to-cmd ./devtools/get-maintainer.sh \
--cc dev@dpdk.org HEAD -4
Currently there is an ugly workaround to be able to use Linux script out
of the kernel tree, later better method can replace it.
