From: Michael Baum:
> The mlx5_compress_qp_setup function makes shifting to the numeric
> constant 1, then sends it as a parameter to rte_calloc function.
>=20
> The rte_calloc function expects to get size_t (64 bits, unsigned) and ins=
tead
> 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 eve=
n though
> the function can get 64-bit argument.
>=20
> Change the size of the numeric constant 1 to 64-bit.
