Subject: [PATCH net] net/mlx4_en:

From: Eric Dumazet <edumazet@...gle.com>

When changing rss key, we do not want to overwrite user provided key
by the one provided by netdev_rss_key_fill(), which is the host random
key generated at boot time.

Fixes: 947cbb0ac242 ("net/mlx4_en: Support for configurable RSS hash function")
