net: dsa: add port fast ageing

2016-09-23T12:38:50+00:00

Today the DSA drivers are in charge of flushing the MAC addresses
associated to a port when its STP state changes from Learning or
Forwarding, to Disabled or Blocking or Listening.

This makes the drivers more complex and hides the generic switch logic.
Introduce a new optional port_fast_age operation to dsa_switch_ops, to
move this logic to the DSA layer and keep drivers simple.

net: dsa: add port STP state helper

2016-09-23T12:38:50+00:00

Add a void helper to set the STP state of a port, checking first if the
required routine is provided by the driver.

net-next: dsa: make the set_addr() operation optional

2016-09-20T08:47:44+00:00

Only 1 of the 3 drivers currently has a set_addr() operation. Make the
set_addr() callback optional to reduce the amount of empty stubs inside
the drivers.

net-next: dsa: fix duplicate invocation of set_addr()

2016-09-20T08:47:44+00:00

commit 83c0afaec7b730b ("net: dsa: Add new binding implementation")
has a duplicate invocation of the set_addr() operation callback. Remove one
of them.

net-next: dsa: add Qualcomm tag RX/TX handler

2016-09-16T08:31:51+00:00

Add support for the 2-bytes Qualcomm tag that gigabit switches such as
the QCA8337/N might insert when receiving packets, or that we need
to insert while targeting specific switch ports. The tag is inserted
directly behind the ethernet header.

net: dsa: rename switch operations structure

2016-08-25T04:45:39+00:00

Now that the dsa_switch_driver structure contains only function pointers
as it is supposed to, rename it to the more appropriate dsa_switch_ops,
uniformly to any other operations structure in the kernel.

No functional changes here, basically just the result of something like:
s/dsa_switch_driver *drv/dsa_switch_ops *ops/g

However keep the {un,}register_switch_driver functions and their
dsa_switch_drivers list as is, since they represent the -- likely to be
deprecated soon -- legacy DSA registration framework.

In the meantime, also fix the following checks from checkpatch.pl to
make it happy with this patch:

    CHECK: Comparison to NULL could be written "!ops"
    #403: FILE: net/dsa/dsa.c:470:
    +	if (ops == NULL) {

    CHECK: Comparison to NULL could be written "ds->ops->get_strings"
    #773: FILE: net/dsa/slave.c:697:
    +		if (ds->ops->get_strings != NULL)

    CHECK: Comparison to NULL could be written "ds->ops->get_ethtool_stats"
    #824: FILE: net/dsa/slave.c:785:
    +	if (ds->ops->get_ethtool_stats != NULL)

    CHECK: Comparison to NULL could be written "ds->ops->get_sset_count"
    #835: FILE: net/dsa/slave.c:798:
    +		if (ds->ops->get_sset_count != NULL)

    total: 0 errors, 0 warnings, 4 checks, 784 lines checked

net: dsa: Allow the DSA driver to indicate the tag protocol

2016-08-23T04:08:08+00:00

DSA drivers may drive different families of switches which need
different tag protocol. Rather than hard code the tag protocol in the
driver structure, have a callback for the DSA core to call.

net: dsa: bcm_sf2: Make it a real platform device driver

2016-08-20T00:15:36+00:00

The Broadcom Starfighter 2 switch driver should be a proper platform
driver, now that the DSA code has been updated to allow that, register a
switch device, feed it with the proper configuration data coming from
Device Tree and register our switch device with DSA.

The bulk of the changes consist in moving what bcm_sf2_sw_setup() did
into the platform driver probe function.

net: dsa: Export suspend/resume functions

2016-08-20T00:15:36+00:00

In preparation for allowing switch drivers to implement system-wide
suspend/resume functions, export dsa_switch_suspend and
dsa_switch_resume() such that these are callable from the appropriate
driver specific suspend/resume functions.
