Subject: [PATCH net-next 5/5] net: dsa: sja1105: Increase priority of CPU-trapped frames
Date: Wed, 29 May 2019 02:56:27 +0300	[thread overview]
Message-ID: <20190528235627.1315-6-olteanv@gmail.com> (raw)
In-Reply-To: <20190528235627.1315-1-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.
