Subject: [PATCH net-next 00/15] DSA miscellaneous cleanups

This is an assorted set of cleanups with the purpose of consolidating
the development work done recently, and preparing the code base for more
changes.

- delete one unnecessary code path for DSA master initialization
- less frequent rtnetlink locking during DSA slave initialization
- symmetric DSA switch tree initialization and teardown
- deleted no-op cross-chip notifier support for MRP and HSR
- struct dsa_port reduced from 576 to 544 bytes, and first cache line a
  bit better organized
- struct dsa_switch from 160 to 136 bytes, and first cache line a bit
  better organized
- struct dsa_switch_tree from 112 to 104 bytes, and first cache line a
  bit better organized

Vladimir Oltean (15):
  net: dsa: reorder PHY initialization with MTU setup in slave.c
  net: dsa: merge rtnl_lock sections in dsa_slave_create
  net: dsa: stop updating master MTU from master.c
  net: dsa: hold rtnl_mutex when calling dsa_master_{setup,teardown}
  net: dsa: first set up shared ports, then non-shared ports
  net: dsa: setup master before ports
  net: dsa: remove cross-chip support for MRP
  net: dsa: remove cross-chip support for HSR
  net: dsa: move dsa_port :: stp_state near dsa_port :: mac
  net: dsa: merge all bools of struct dsa_port into a single u8
  net: dsa: move dsa_port :: type near dsa_port :: index
  net: dsa: merge all bools of struct dsa_switch into a single u32
  net: dsa: make dsa_switch :: num_ports an unsigned int
  net: dsa: move dsa_switch_tree :: ports and lags to first cache line
  net: dsa: combine two holes in struct dsa_switch_tree
