Subject: [PATCH net-next v3 0/8] net: dsa: vsc73xx: Make vsc73xx usable

This patch series focuses on making vsc73xx usable.

The first patch was added in v2; it switches from a poll loop to
read_poll_timeout.

The second patch is a simple conversion to phylink because adjust_link won't
work anymore.

The third patch introduces a definition with the maximum number of ports to
avoid using magic numbers.

The fourth patch implements port state configuration, which is required for
bridge functionality. STP frames are not forwarded at this moment. BPDU frames
are only forwarded from/to the PI/SI interface. For more information, see chapter
2.7.1 (CPU Forwarding) in the datasheet.

Patches 5-8 provide a basic implementation of tag8021q functionality with QinQ
support, without VLAN filtering in the bridge and simple VLAN awareness in VLAN
filtering mode.
