Subject: [PATCH v2 8/8] wil6210: add debugfs 'mids' file
Date: Mon, 26 Feb 2018 20:12:18 +0200 [thread overview]
Message-ID: <1519668738-16912-9-git-send-email-merez@codeaurora.org> (raw)
In-Reply-To: <1519668738-16912-1-git-send-email-merez@codeaurora.org>
From: Lior David <liord@codeaurora.org>
Added a new debugfs file 'mids' to print the list of
virtual interfaces by MAC ID (MID). Allows mapping
between the internal MID used by FW and the actual
network interface used by the VIF. This is needed by
debugging tools.
