Subject: [PATCH 42/55] staging: wfx: remove unnecessary EDCA initialisation
Date: Mon, 16 Dec 2019 17:03:55 +0000 [thread overview]
Message-ID: <20191216170302.29543-43-Jerome.Pouiller@silabs.com> (raw)
In-Reply-To: <20191216170302.29543-1-Jerome.Pouiller@silabs.com>
From: Jérôme Pouiller <jerome.pouiller@silabs.com>
mac80211 already call wfx_conf_tx() on every VIF instanciation. So, the
driver does not need to do it.
Note that current code did dirty things with wvif->edca_params. This
struct was initialized, but only 'queue_id' was really used. The other
members are only used to store temporary values.
