Subject: [dpdk-dev] [PATCH 3/3] doc/windows: clarify installation for MinGW-w64
Date: Sun, 21 Jun 2020 01:35:44 +0300
Message-ID: <20200620223544.24070-4-dmitry.kozliuk@gmail.com> (raw)
In-Reply-To: <20200620223544.24070-1-dmitry.kozliuk@gmail.com>

Provide a more direct link for installer download and clarify thread
model choice during installation. As pthread is not a requirement,
remove notice about its possible runtime dependency.
