Subject: Re: [dpdk-dev] [PATCH] doc: add kernel version deprecation notice
Date: Thu, 24 May 2018 22:53:14 +0200	[thread overview]
Message-ID: <19336935.ml6P7h8xrF@xps> (raw)
In-Reply-To: <20180214114415.GA1880@bricha3-MOBL3.ger.corp.intel.com>

There was no decision about changing the kernel requirements.
We need to restart the discussion and take a decision for

Decision can be taken in technical board (Cc).
