Subject: [PATCH 897/898] net: dsa: mv88e6xxx: pass mv88e6xxx_chip structure to
 port_max_speed_mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some switches families have minor differences on supported link speed for
ports. Instead of redefining a new port_max_speed_mode for each different
configuration, allow to pass mv88e6xxx_chip structure to allow
differentiating those chips by known chip id

Update one more instance of port_max_speed_mode that 5.15 has.
