Subject: [dpdk-dev] [PATCH v3 2/7] net/mlx5: fix work queue array size
Date: Tue, 24 Oct 2017 17:18:13 +0200	[thread overview]
Message-ID: <2292f63b3496fd64b94924d660fc66f671b325ef.1508857992.git.nelio.laranjeiro@6wind.com> (raw)
In-Reply-To: <cover.1508857992.git.nelio.laranjeiro@6wind.com>
In-Reply-To: <cover.1508857992.git.nelio.laranjeiro@6wind.com>

Indirection table size must be in log to communicate with verbs when the
number of queue is not a power of two, the maximum indirection table size
is use, but not converted to log2.  This makes a memory corruption.

Fixes: 4c7a0f5ff876 ("net/mlx5: make indirection tables shareable")
