net: dsa: remove unnecessary phy*.h includes

2017-02-10T18:51:04+00:00

Including phy.h and phy_fixed.h into net/dsa.h causes phy*.h to be an
unnecessary dependency for quite a large amount of the kernel.  There's
very little which actually requires definitions from phy.h in net/dsa.h
- the include itself only wants the declaration of a couple of
structures and IFNAMSIZ.

Add linux/if.h for IFNAMSIZ, declarations for the structures, phy.h to
mv88e6xxx.h as it needs it for phy_interface_t, and remove both phy.h
and phy_fixed.h from net/dsa.h.

This patch reduces from around 800 files rebuilt to around 40 - even
with ccache, the time difference is noticable.

net: dsa: Add support for platform data

2017-02-07T15:51:45+00:00

Allow drivers to use the new DSA API with platform data. Most of the
code in net/dsa/dsa2.c does not rely so much on device_nodes and can get
the same information from platform_data instead.

We purposely do not support distributed configurations with platform
data, so drivers should be providing a pointer to a 'struct
dsa_chip_data' structure if they wish to communicate per-port layout.

Multiple CPUs port could potentially be supported and dsa_chip_data is
extended to receive up to one reference to an upstream network device
per port described by a dsa_chip_data structure.

dsa_dev_to_net_device() increments the network device's reference count,
so we intentionally call dev_put() to be consistent with the DT-enabled
path, until we have a generic notifier based solution.

net: dsa: Rename and export dev_to_net_device()

2017-02-07T15:51:45+00:00

In preparation for using this function in net/dsa/dsa2.c, rename the function
to make its scope DSA specific, and export it.

net: dsa: introduce bridge notifier

2017-02-06T21:53:29+00:00

A slave device will now notify the switch fabric once its port is
bridged or unbridged, instead of calling directly its switch operations.

This code allows propagating cross-chip bridging events in the fabric.

net: dsa: add switch notifier

2017-02-06T21:53:29+00:00

Add a notifier block per DSA switch, registered against a notifier head
in the switch fabric they belong to.

This infrastructure will allow to propagate fabric-wide events such as
port bridging, VLAN configuration, etc. If a DSA switch driver cares
about cross-chip configuration, such events can be caught.

net: dsa: Add plumbing for port mirroring

2017-01-30T20:55:46+00:00

Add necessary plumbing at the slave network device level to have switch
drivers implement ndo_setup_tc() and most particularly the cls_matchall
classifier. We add support for two switch operations:

port_add_mirror and port_del_mirror() which configure, on a per-port
basis the mirror parameters requested from the cls_matchall classifier.

Code is largely borrowed from the Mellanox Spectrum switch driver.

net: dsa: pass bridge device when a port leaves

2017-01-29T23:42:46+00:00

Upon reception of the NETDEV_CHANGEUPPER, a leaving port is already
unbridged, so reflect this by assigning the port's bridge_dev pointer to
NULL before calling the port_bridge_leave DSA driver operation.

Now that the bridge_dev pointer is exposed to the drivers, reflecting
the current state of the DSA switch fabric is necessary for the drivers
to adjust their port based VLANs correctly.

Pass the bridge device pointer to the port_bridge_leave operation so
that drivers have all information to re-program their chips properly,
and do not need to cache it anymore.

Move the bridge_dev pointer from dsa_slave_priv to dsa_port so that DSA
drivers can access this information and remove the need to cache it.

net: dsa: add ds and index to dsa_port

2017-01-29T23:42:46+00:00

Add the physical switch instance and port index a DSA port belongs to to
the dsa_port structure.

That can be used later to retrieve information about a physical port
when configuring a switch fabric, or lighten up struct dsa_slave_priv.
