Subject: [PATCH net-next v3 0/4] net: dsa: Multi-CPU ground work (v3)

Hi all,

This patch series prepares the ground for adding mutliple CPU port support to
DSA, and starts by removing redundant pieces of information such as
master_netdev which is cpu_dp->ethernet. Finally drivers are moved away from
directly accessing ds->dst->cpu_dp and use appropriate helper functions.

Note that if you have Device Tree blobs/platform configurations that are
currently listing multiple CPU ports, the proposed behavior in
dsa_ds_get_cpu_dp() will be to return the last bit set in ds->cpu_port_mask.

Future plans include:
- making dst->cpu_dp a flexible data structure (array, list, you name it)
- having the ability for drivers to return a default/preferred CPU port (if
  necessary)

Changes in v3:

- removed the last patch since it causes problems with bcm_sf2/b53 in a
  dual-CPU case (root cause known, proper fix underway)

- removed dsa_ds_get_cpu_dp()

Changes in v2:

- added Reviewed-by tags
- assign port->cpu_dp earlier before ops->setup() has run

Florian Fainelli (5):
  net: dsa: Remove master_netdev and use dst->cpu_dp->netdev
  net: dsa: Relocate master ethtool operations
  net: dsa: Associate slave network device with CPU port
  net: dsa: Introduce dsa_dst_get_cpu_dp()
  net: dsa: Stop accessing ds->dst->cpu_dp in drivers
