[dpdk-dev] [PATCH 2/2] net/mlx5: fix RSS key len query

[Shahaf Shuler]

The RSS key length returned by rte_eth_dev_info_get command was taken
from the
PMD private structure. This structure initialization was done only after
the port configuration.

Considering Mellanox device supports only 40B long RSS key, reporting
the fixed number instead.

Fixes: 29c1d8bb3e79 ("net/mlx5: handle a single RSS hash key for all protocols")
