[PATCH v2 net-next 10/10] net: dsa: sja1105: Increase priority of CPU-trapped frames

[Vladimir Oltean <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.
