Subject: [PATCH 2/2] ath9k: disable RNG by default
Date: Tue, 9 Aug 2016 15:02:27 +0800 [thread overview]
Message-ID: <1470726147-30095-2-git-send-email-miaoqing@codeaurora.org> (raw)
In-Reply-To: <1470726147-30095-1-git-send-email-miaoqing@codeaurora.org>
From: Miaoqing Pan <miaoqing@codeaurora.org>
ath9k RNG will dominates all the noise sources from the real HW
RNG, disable it by default. But we strongly recommand to enable
it if the system without HW RNG, especially on embedded systems.
