Subject: [PATCH v2 05/65] staging: wfx: simplify hif_set_tx_rate_retry_policy() usage
Date: Wed, 15 Jan 2020 13:54:09 +0000
Message-ID: <20200115135338.14374-6-Jerome.Pouiller@silabs.com> (raw)
In-Reply-To: <20200115135338.14374-1-Jerome.Pouiller@silabs.com>

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

The structure hif_mib_set_tx_rate_retry_policy come from hardware
API. It is not intended to be manipulated in upper layers of the driver.

So, this patch relocate handling of this structure to
hif_set_tx_rate_retry_policy() (the low level function).
