Subject: [dpdk-stable] [PATCH 6/7] regex/mlx5: improve constants type in QP buffers creation
Date: Wed, 18 Nov 2020 17:00:10 +0000 [thread overview]
Message-ID: <1605718811-18652-6-git-send-email-michaelba@nvidia.com> (raw)
In-Reply-To: <1605718811-18652-1-git-send-email-michaelba@nvidia.com>
The constant representing the size of the metadata is defined as a
regular number (32-bit signed), even though all of its uses request an
unsigned int variable.
Similarly the constant representing the maximal output is also defined
as a regular number, even though all of its uses request an unsigned int
variable.
Change the type of the above constants to unsigned.
Fixes: 5f41b66d12cd ("regex/mlx5: setup fast path")
