Subject: [PATCH 07/16] staging: wfx: field operational_rate_set is ignored by firmware
Date: Mon, 20 Apr 2020 18:03:02 +0200	[thread overview]
Message-ID: <20200420160311.57323-8-Jerome.Pouiller@silabs.com> (raw)
In-Reply-To: <20200420160311.57323-1-Jerome.Pouiller@silabs.com>

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

The field bss_params.operational_rate_set is ignore by the firmware. It
is not necessary to send it. This change greatly simplify
wfx_join_finalize(). It is no more necessary to get sta and it allow to
save a RCU.
