Subject: [dpdk-dev] [PATCH 5/5] net/mlx5: fix Memory Region boundary checks
Date: Tue, 23 Jan 2018 19:08:23 +0200	[thread overview]
Message-ID: <4a20606b752722f043f1440bb7c8be4ea04b1159.1516727100.git.shahafs@mellanox.com> (raw)
In-Reply-To: <cover.1516727100.git.shahafs@mellanox.com>

Since commit f81ec748434b ("net/mlx5: fix memory region lookup") the
memory regions (MR) are no longer overlaps.

Comparing the end address of the MR should be exclusive, otherwise two
contiguous MRs may cause wrong matching.

Fixes: f81ec748434b ("net/mlx5: fix memory region lookup")
Cc: yskoh@mellanox.com
