Subject: [PATCH v3 net-next 15/17] net: dsa: sja1105: Increase priority of CPU-trapped frames
Date: Tue, 4 Jun 2019 20:07:54 +0300 [thread overview]
Message-ID: <20190604170756.14338-16-olteanv@gmail.com> (raw)
In-Reply-To: <20190604170756.14338-1-olteanv@gmail.com>
Without noticing any particular issue, this patch ensures that
management traffic is treated with the maximum priority on RX by the
switch. This is generally desirable, as the driver keeps a state
machine that waits for metadata follow-up frames as soon as a management
frame is received. Increasing the priority helps expedite the reception
(and further reconstruction) of the RX timestamp to the driver after the
MAC has generated it.
