#1735052 — [PATCH net-next 0/4] net: dsa: move master ethtool code

The DSA core overrides the master device's ethtool_ops structure so that
it can inject statistics and such of its dedicated switch CPU port.

This ethtool code is currently called on unnecessary conditions or
before the master interface and its switch CPU port get wired up.
This patchset fixes this.

Similarly to slave.c where the DSA slave net_device is the entry point
of the dsa_slave_* functions, this patchset also isolates the master's
ethtool code in a new master.c file, where the DSA master net_device is
the entry point of the dsa_master_* functions.

This is a first step towards better control of the master device and
support for multiple CPU ports.

Vivien Didelot (4):
  net: dsa: remove copy of master ethtool_ops
  net: dsa: setup master ethtool unconditionally
  net: dsa: setup master ethtool after dsa_ptr
  net: dsa: move master ethtool code

#1735057 — [PATCH net-next 4/4] net: dsa: move master ethtool code

DSA overrides the master device ethtool ops, so that it can inject stats
from its dedicated switch CPU port as well.

The related code is currently split in dsa.c and slave.c, but it only
scopes the master net device. Move it to a new master.c DSA core file.

This file will be later extented with master net device specific code.

#1735058 — [PATCH net-next 2/4] net: dsa: setup master ethtool unconditionally

When a DSA switch tree is meant to be applied, it already has a CPU
port. Thus remove the condition of dst->cpu_dp.

Moreover, the next lines access dst->cpu_dp unconditionally.

* ethtool -S eth0 -> switch port CPU stats are still correctly overlayed
* ethtool -s gphy wol g -> both switch port and CPU port correctly
enable WoL
* ethtool -i eth0 -> driver still reports correct information

Thanks!
