Subject: [PATCH net-next v2 0/6] net: dsa: enable and disable all ports

The DSA stack currently calls the .port_enable and .port_disable switch
callbacks for slave ports only. However, it is useful to call them for all
port types. For example this allows some drivers to delay the optimization
of power consumption after the switch is setup. This can also help reducing
the setup code of drivers a bit.

The first DSA core patches enable and disable all ports of a switch, regardless
their type. The last mv88e6xxx patches remove redundant code from the driver
setup and the said callbacks, now that they handle SERDES power for all ports.

Changes in v2: do not guard .port_disable for broadcom switches.

Vivien Didelot (6):
  net: dsa: use a single switch statement for port setup
  net: dsa: do not enable or disable non user ports
  net: dsa: enable and disable all ports
  net: dsa: mv88e6xxx: do not change STP state on port disabling
  net: dsa: mv88e6xxx: enable SERDES after setup
  net: dsa: mv88e6xxx: wrap SERDES IRQ in power function
