   4 Subject: [PATCH 897/898] net: dsa: mv88e6xxx: pass mv88e6xxx_chip structure to
   5  port_max_speed_mode
   6 MIME-Version: 1.0

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