[PATCH net-next v4 0/4] net: dsa: Multi-CPU ground work (v4)

[Florian Fainelli <f.fainelli@gmail.com>]

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 v4:

- fixed build warning with NETPOLL enabled

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
