Merge branch 'dsa-cross-chip-notifier-cleanup'

Vladimir Oltean says:

====================
DSA cross-chip notifier cleanups

This patch set makes the following improvements:

- Cross-chip notifiers pass a switch index, port index, sometimes tree
  index, all as integers. Sometimes we need to recover the struct
  dsa_port based on those integers. That recovery involves traversing a
  list. By passing directly a pointer to the struct dsa_port we can
  avoid that, and the indices passed previously can still be obtained
  from the passed struct dsa_port.

- Resetting VLAN filtering on a switch has explicit code to make it run
  on a single switch, so it has no place to stay in the cross-chip
  notifier code. Move it out.

- Changing the MTU on a user port affects only that single port, yet the
  code passes through the cross-chip notifier layer where all switches
  are notified. Avoid that.

- Other related cosmetic changes in the MTU changing procedure.

Apart from the slight improvement in performance given by
(a) doing less work in cross-chip notifiers
(b) emitting less cross-chip notifiers
we also end up with about 100 less lines of code.
