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: Remove switchdev_ops

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

Now that we have converted all possible callers to using a switchdev
notifier for attributes we do not have a need for implementing
switchdev_ops anymore, and this can be removed from all drivers the
net_device structure.

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_port_attr_get()

2019-02-21T22:55:14+00:00

With the bridge no longer calling switchdev_port_attr_get() to obtain
the supported bridge port flags from a driver but instead trying to set
the bridge port flags directly and relying on driver to reject
unsupported configurations, we can effectively get rid of
switchdev_port_attr_get() entirely since this was the only place where
it was called.

net: Remove SWITCHDEV_ATTR_ID_PORT_BRIDGE_FLAGS_SUPPORT

2019-02-21T22:55:14+00:00

Now that we have converted the bridge code and the drivers to check for
bridge port(s) flags at the time we try to set them, there is no need
for a get() -> set() sequence anymore and
SWITCHDEV_ATTR_ID_PORT_BRIDGE_FLAGS_SUPPORT therefore becomes unused.

net: switchdev: Add PORT_PRE_BRIDGE_FLAGS

2019-02-21T22:55:13+00:00

In preparation for removing switchdev_port_attr_get(), introduce
PORT_PRE_BRIDGE_FLAGS which will be called through
switchdev_port_attr_set(), in the caller's context (possibly atomic) and
which must be checked by the switchdev driver in order to return whether
the operation is supported or not.

This is entirely analoguous to how the BRIDGE_FLAGS_SUPPORT works,
except it goes through a set() instead of get().

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.
