Subject: [dpdk-dev] [PATCH 6/6] net/nfp: set dma mask
Date: Tue, 26 Jun 2018 18:37:33 +0100	[thread overview]
Message-ID: <1530034653-28299-7-git-send-email-alejandro.lucero@netronome.com> (raw)
In-Reply-To: <1530034653-28299-1-git-send-email-alejandro.lucero@netronome.com>

NFP 4000/6000 devices can not use iova addresses requiring more
than 40 bits. This patch sets a dma mask for avoiding hugepages
with iova requiring more than those 40 bits.
