Subject: [PATCH v2 42/65] staging: wfx: do not update uapsd if not necessary
Date: Wed, 15 Jan 2020 13:55:03 +0000
Message-ID: <20200115135338.14374-43-Jerome.Pouiller@silabs.com> (raw)
In-Reply-To: <20200115135338.14374-1-Jerome.Pouiller@silabs.com>

From: Jérôme Pouiller <jerome.pouiller@silabs.com>

wfx_conf_tx() is called for each queue. On every call, the function
updates UAPSD mask and PM mode for all queues. It is a pity since the
UAPSD configuration very rarely changes and it makes exchanges between
the host and the chip more difficult to track.

This patch avoid to update UAPSD and Power Mode in most usual cases.
