Subject: [PATCH 14/32] staging: wfx: do not use link_map_cache to track CAB
Date: Wed,  1 Apr 2020 13:03:47 +0200	[thread overview]
Message-ID: <20200401110405.80282-15-Jerome.Pouiller@silabs.com> (raw)
In-Reply-To: <20200401110405.80282-1-Jerome.Pouiller@silabs.com>

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

Since we do not track power save status of the stations anymore,
link_map_cache is now only used to track "Content After (DTIM) Beacon".
We prefer to rely on flags from tx_info. So we will be able to drop
link_map_cache.
