Subject: [PATCH v2 3/6] wcn36xx: Increase number of TX retries
Date: Fri, 24 Jul 2020 12:20:49 +0200	[thread overview]
Message-ID: <1595586052-16081-4-git-send-email-loic.poulain@linaro.org> (raw)
In-Reply-To: <1595586052-16081-1-git-send-email-loic.poulain@linaro.org>

Increase the short/long retry limit to 15 in order to impove TX
robustness in noisy/busy environment. 15 is the default value
defined in the downstream driver. Observed number of ack timeout
is reduced with this change.
