net: dsa: Associate slave network device with CPU port

2017-06-13T20:35:03+00:00

In preparation for supporting multiple CPU ports with DSA, have the
dsa_port structure know which CPU it is associated with. This will be
important in order to make sure the correct CPU is used for transmission
of the frames. If not for functional reasons, for performance (e.g: load
balancing) and forwarding decisions.

net: dsa: Relocate master ethtool operations

2017-06-13T20:35:02+00:00

Relocate master_ethtool_ops and master_orig_ethtool_ops into struct
dsa_port in order to be both consistent, and make things self contained
within the dsa_port structure.

This is a preliminary change to supporting multiple CPU port interfaces.

net: dsa: Remove master_netdev and use dst->cpu_dp->netdev

2017-06-13T20:35:02+00:00

In preparation for supporting multiple CPU ports, remove
dst->master_netdev and ds->master_netdev and replace them with only one
instance of the common object we have for a port: struct
dsa_port::netdev. ds->master_netdev is currently write only and would be
helpful in the case where we have two switches, both with CPU ports, and
also connected within each other, which the multi-CPU port patch series
would address.

While at it, introduce a helper function used in net/dsa/slave.c to
immediately get a reference on the master network device called
dsa_master_netdev().

net: dsa: Initialize all CPU and enabled ports masks in dsa_ds_parse()

2017-06-05T00:05:15+00:00

There was no reason for duplicating the code that initializes
ds->enabled_port_mask in both dsa_parse_ports_dn() and
dsa_parse_ports(), instead move this to dsa_ds_parse() which is early
enough before ops->setup() has run.

While at it, we can now make dsa_is_cpu_port() check ds->cpu_port_mask
which is a step towards being multi-CPU port capable.

net: dsa: remove dsa_uses_tagged_protocol

2017-06-01T21:34:56+00:00

Since dev->dsa_ptr is a pointer to a dsa_switch_tree, there is no need
to have another inline helper just to check rcv.

Remove dsa_uses_tagged_protocol and check dsa_ptr && dsa_ptr->rcv
together at the same time.

net: dsa: comment hot path requirements

2017-06-01T21:34:56+00:00

The DSA layer uses inline helpers and copy of the tagging functions for
faster access in hot path. Add comments to detail that.

net: dsa: remove dev arg of dsa_register_switch

2017-05-31T16:35:43+00:00

The current dsa_register_switch function takes a useless struct device
pointer argument, which always equals ds->dev.

Drivers either call it with ds->dev, or with the same device pointer
passed to dsa_switch_alloc, which ends up being assigned to ds->dev.

This patch removes the second argument of the dsa_register_switch and
_dsa_register_switch functions.

net: dsa: move notifier info to private header

2017-05-22T23:37:32+00:00

The DSA notifier events and info structure definitions are not meant for
DSA drivers and users, but only used internally by the DSA core files.

Move them from the public net/dsa.h file to the private dsa_priv.h file.

Also use this opportunity to turn the events into an anonymous enum,
because we don't care about the values, and this will prevent future
conflicts when adding (and sorting) new events.
