Subject: [dpdk-stable] [PATCH 1/6] eal: add internal dma mask
Date: Tue, 26 Jun 2018 18:37:28 +0100 [thread overview]
Message-ID: <1530034653-28299-2-git-send-email-alejandro.lucero@netronome.com> (raw)
In-Reply-To: <1530034653-28299-1-git-send-email-alejandro.lucero@netronome.com>
Devices can have addressing limitations and an internal dma mask
will track the more restrictive dma mask set by a device.
