[dpdk-dev] [PATCH 4/4] net/mlx5: fix constant type in MP allocation

[Michael Baum <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.
