[PATCH net-next 0/6] Improvement for DSA cross-chip setups

From: Vladimir Oltean <vladimir.oltean@nxp.com>

This series improves some aspects in multi-switch DSA tree topologies:
- better device tree validation
- better handling of MTU changes
- better handling of multicast addresses
- removal of some unused code

Vladimir Oltean (6):
  net: dsa: assert uniqueness of dsa,member properties
  net: dsa: export the dsa_port_is_{user,cpu,dsa} helpers
  net: dsa: execute dsa_switch_mdb_add only for routing port in
    cross-chip topologies
  net: dsa: calculate the largest_mtu across all ports in the tree
  net: dsa: targeted MTU notifiers should only match on one port
  net: dsa: remove cross-chip support from the MRP notifiers
