switchdev: Remove unused transaction item queue

2019-03-02T05:35:19+00:00

There are no more in tree users of the
switchdev_trans_item_{dequeue,enqueue} or switchdev_trans_item structure
in the kernel since commit 00fc0c51e35b ("rocker: Change world_ops API
and implementation to be switchdev independant").

Remove this unused code and update the documentation accordingly since.

net: switchdev: Replace port attr set SDO with a notification

2019-02-27T20:39:56+00:00

Drop switchdev_ops.switchdev_port_attr_set. Drop the uses of this field
from all clients, which were migrated to use switchdev notification in
the previous patches.

Add a new function switchdev_port_attr_notify() that sends the switchdev
notifications SWITCHDEV_PORT_ATTR_SET and calls the blocking (process)
notifier chain.

We have one odd case within net/bridge/br_switchdev.c with the
SWITCHDEV_ATTR_ID_PORT_PRE_BRIDGE_FLAGS attribute identifier that
requires executing from atomic context, we deal with that one
specifically.

Drop __switchdev_port_attr_set() and update switchdev_port_attr_set()
likewise.

switchdev: Add SWITCHDEV_PORT_ATTR_SET

2019-02-27T20:39:55+00:00

In preparation for allowing switchdev enabled drivers to veto specific
attribute settings from within the context of the caller, introduce a
new switchdev notifier type for port attributes.

switchdev: Complete removal of switchdev_port_attr_get()

2019-02-25T06:31:41+00:00

We have no more in tree users of switchdev_port_attr_get() after
d0e698d57a94 ("Merge branch 'net-Get-rid-of-switchdev_port_attr_get'")
so completely remove the function signature and body.

net: Get rid of SWITCHDEV_ATTR_ID_PORT_PARENT_ID

2019-02-06T22:17:03+00:00

Now that we have a dedicated NDO for getting a port's parent ID, get rid
of SWITCHDEV_ATTR_ID_PORT_PARENT_ID and convert all callers to use the
NDO exclusively. This is a preliminary change to getting rid of
switchdev_ops eventually.

switchdev: Add extack argument to call_switchdev_notifiers()

2019-01-17T23:18:47+00:00

A follow-up patch will enable vetoing of FDB entries. Make it possible
to communicate details of why an FDB entry is not acceptable back to the
user.

net: switchdev: Add extack to switchdev_handle_port_obj_add() callback

2018-12-13T00:34:22+00:00

Drivers use switchdev_handle_port_obj_add() to handle recursive descent
through lower devices. Change this function prototype to take add_cb
that itself takes an extack argument. Decode extack from
switchdev_notifier_port_obj_info and pass it to add_cb.

Update mlxsw and ocelot drivers which use this helper.

net: switchdev: Add extack to struct switchdev_notifier_info

2018-12-13T00:34:22+00:00

In order to pass extack to the drivers that need it, add an extack field
to struct switchdev_notifier_info, and an extack argument to the
function call_switchdev_blocking_notifiers(). Also add a helper function
switchdev_notifier_info_to_extack().

net: switchdev: Add extack argument to switchdev_port_obj_add()

2018-12-13T00:34:21+00:00

After the previous patch, bridge driver has extack argument available to
pass to switchdev. Therefore extend switchdev_port_obj_add() with this
argument, updating all callers, and passing the argument through to
switchdev_port_obj_notify().
