Subject: [PATCH 4.2 15/30] net/mlx4_en: really allow to change RSS key
Date: Thu, 1 Oct 2015 11:21:37 +0200 [thread overview]
Message-ID: <20151001092038.855318266@linuxfoundation.org> (raw)
In-Reply-To: <20151001092038.213304276@linuxfoundation.org>
4.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eric Dumazet <edumazet@google.com>
[ Upsteam commit 4671fc6d47e0a0108fe24a4d830347d6a6ef4aa7 ]
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")
