Subject: [PATCH 05/21] wil6210: fix invalid sta statistics update
Date: Fri, 22 Feb 2019 16:21:03 +0200 [thread overview]
Message-ID: <1550845279-16103-6-git-send-email-merez@codeaurora.org> (raw)
In-Reply-To: <1550845279-16103-1-git-send-email-merez@codeaurora.org>
From: Dedy Lansky <dlansky@codeaurora.org>
Upon status ring handling, in case there are both unicast and
multicast (cid == max) status messages to handle, wrong sta statistics
might get updated.
Fix this by setting stats to NULL upon invalid cid
(e.g. == max_assoc_sta).
