Subject: [patch net-next RFC 0/8] net: expose switch ID via devlink

From: Jiri Pirko <jiri@...lanox.com>

To provide visibility of the ports, as discussed this week, this
patchset exposes switch ID for devlink ports, which are part of a
switch. The rest of the ports if any (in case of sr-iov for example)
do not set switch ID.

Note that I send this as RFC because I don't have the NFP bits correct.
The switch ID should be only set for the eswitch ports (representors).
Jakub, could you please help with this?

As a follow-up I also plan to add devlink_port_attrs_set to all users
of ndo_get_port_parent_id and ndo_get_phys_port_name and remove these
ndos completely. But that also depends on Jakub's patchset which
introduces PF and VF port flavours.

Jiri Pirko (8):
  net: devlink: convert devlink_port_attrs bools to bits
  net: devlink: extend port attrs for switch ID
  net: devlink: introduce devlink_compat_switch_id_get() helper
  mlxsw: Pass switch ID through devlink_port_attrs_set()
  mlxsw: Remove ndo_get_port_parent_id implementation
  nfp: pass switch ID through devlink_port_attrs_set()
  nfp: register devlink port before netdev
  nfp: remove ndo_get_port_parent_id implementation
