Subject: [PATCH 16/32] staging: wfx: do not rely anymore on link_id to choose packet in queue
Date: Wed,  1 Apr 2020 13:03:49 +0200	[thread overview]
Message-ID: <20200401110405.80282-17-Jerome.Pouiller@silabs.com> (raw)
In-Reply-To: <20200401110405.80282-1-Jerome.Pouiller@silabs.com>

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

link_id was expected to contain identifier of a station. It was also
used to mark frames that has to sent after dtim. We do not use the
further purpose. For the last purpose, we can directly check the flag
value in tx_info.
