[dpdk-dev] [PATCH v3 4/5] net/mlx5: fix RSS RETA update

[Maxime Coquelin <maxime.coquelin@redhat.com>]

This patch fixes RETA updating for entries above 64.
Without ithat, these entries are never updated as
calculated mask value will always be 0.

Fixes: 634efbc2c8c0 ("mlx5: support RETA query and update")
