Subject: [dpdk-stable] [PATCH 4/4] net/mlx5: fix constant type in MP allocation
Date: Tue, 1 Jun 2021 10:11:22 +0300
Message-ID: <20210601071122.1612432-4-michaelba@nvidia.com> (raw)
In-Reply-To: <20210601071122.1612432-1-michaelba@nvidia.com>

The mlx5_mprq_alloc_mp function makes shifting to the numeric constant
1, for sending it as a parameter to rte_mempool_create function.

The rte_mempool_create function expects to get void pointer (64 bits,
uintptr_t) and instead gets a 32-bit variable, because the numeric
constant size is a 32-bit.
In case the shift is greater than 32 the variable will lose its value
even though the function can get 64-bit argument.

Change the size of the numeric constant 1 to 64-bit.

Fixes: 3a22f3877c9d ("net/mlx5: replace external mbuf shared memory")
