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-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: remove ds_to_priv

Access the priv member of the dsa_switch structure directly, instead of
having an unnecessary helper.

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: Export suspend/resume functions

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.

net: dsa: support switchdev ageing time attr

2016-07-20T02:42:01+00:00

Add a new function for DSA drivers to handle the switchdev
SWITCHDEV_ATTR_ID_BRIDGE_AGEING_TIME attribute.

The ageing time is passed as milliseconds.

Also because we can have multiple logical bridges on top of a physical
switch and ageing time are switch-wide, call the driver function with
the fastest ageing time in use on the chip instead of the requested one.

net: dsa: initialize the routing table

2016-07-09T03:59:49+00:00

The routing table of every switch in a tree is currently initialized to
all zeros. This is an issue since 0 is a valid port number.

Add a DSA_RTABLE_NONE=-1 constant to initialize the signed values of the
routing table pointing to other switches.

This fixes the device mapping of the mv88e6xxx driver where the port
pointing to the switch itself and to non-existent switches was wrongly
configured to be 0. It is now set to the expected 0xf value.

net: dsa: Initialize CPU port ethtool ops per tree

2016-06-08T18:23:42+00:00

Now that we can properly support multiple distinct trees in the system,
using a global variable: dsa_cpu_port_ethtool_ops is getting clobbered
as soon as the second switch tree gets probed, and we don't want that.

We need to move this to be dynamically allocated, and since we can't
really be comparing addresses anymore to determine first time
initialization versus any other times, just move this to dsa.c and
dsa2.c where the remainder of the dst/ds initialization happens.

The operations teardown restores the master netdev's ethtool_ops to its
original ethtool_ops pointer (typically within the Ethernet driver)
