[dpdk-dev] [PATCH] doc: note min required kernel version increase for 19.02

[Kevin Traynor <ktraynor@redhat.com>]

Updating docs to reflect decision made at the techboard
that the min kernel version should be bumped from 3.2 to
the latest longterm stable release (3.16), but that
compatiblity for commonly used distribution kernels should
be kept also.

I namechecked RHEL/CentOS 7 because they have a 3.10 based kernel and
were discussed. I can add others if requested, but not needed if their
base version is >= 3.16.

Not discussed at techboard, but I added that the change will happen for
19.02, so that any impacted users have some time and an LTS before the
change. Can change that if required.
