Subject: [dpdk-dev] [PATCH v2 1/7] mem: fix call to DMA mask check
Date: Thu,  1 Nov 2018 19:53:24 +0000	[thread overview]
Message-ID: <20181101195330.19464-2-alejandro.lucero@netronome.com> (raw)
In-Reply-To: <20181101195330.19464-1-alejandro.lucero@netronome.com>

The param needs to be the maskbits and not the mask.

Fixes: 223b7f1d5ef6 ("mem: add function for checking memseg IOVA")
