Subject: [PATCH v2 02/10] rt2800: identify station based on status WCID
Date: Wed, 15 Feb 2017 10:25:05 +0100 [thread overview]
Message-ID: <1487150713-3510-3-git-send-email-sgruszka@redhat.com> (raw)
In-Reply-To: <1487150713-3510-1-git-send-email-sgruszka@redhat.com>
Add framework to identify sta based on tx status WCID. This is currently
not used, will start be utilized in the future patch.
