Subject: common/mlx5: avoid class constructor priority
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=82088001631d6255f49df5ecac2ebd2bcfc8126e;p=dpdk.git

common/mlx5: avoid class constructor priority

mlx5_common is shared library between mlx5 net, VDPA and regex PMD.
It is better to use common initialization helper instead of using
RTE_PRIORITY_CLASS priority.
