[dpdk-stable] [PATCH v2 62/67] net/mlx4: avoid constant recreations in function

[Yongseok Koh]

From: Ophir Munk <ophirmu at mellanox.com>

[ upstream commit cbd737416c34c2f71227ac450db2c85a789dac30 ]

Function mlx4_conv_rss_types() contains constant arrays variables
which are recreated with every call to the function. By changing the
arrays definitions from "const" to "static const" these recreations
can be saved.
