Subject: [PATCH net-next 3/6] net: qualcomm: rmnet: Allow only one rmnet dev per muxid per real dev
Date: Sun, 3 Dec 2017 23:37:05 -0700 [thread overview]
Message-ID: <1512369428-20455-4-git-send-email-subashab@codeaurora.org> (raw)
In-Reply-To: <1512369428-20455-1-git-send-email-subashab@codeaurora.org>
Upon de-multiplexing data from one real dev, the packets can be sent
to an unique rmnet device for a given mux id.
