net: flow_offload: add flow_block structure and use it

2019-07-20T04:27:45+00:00

This object stores the flow block callbacks that are attached to this
block. Update flow_block_cb_lookup() to take this new object.

This patch restores the block sharing feature.

net: flow_offload: remove netns parameter from flow_block_cb_alloc()

2019-07-20T04:27:45+00:00

No need to annotate the netns on the flow block callback object,
flow_block_cb_is_busy() already checks for used blocks.

net: dsa: add support for BRIDGE_MROUTER attribute

2019-07-09T21:49:34+00:00

This patch adds support for enabling or disabling the flooding of
unknown multicast traffic on the CPU ports, depending on the value
of the switchdev SWITCHDEV_ATTR_ID_BRIDGE_MROUTER attribute.

The current behavior is kept unchanged but a user can now prevent
the CPU conduit to be flooded with a lot of unregistered traffic that
the network stack needs to filter in software with e.g.:

    echo 0 > /sys/class/net/br0/multicast_router

net: flow_offload: add flow_block_cb_is_busy() and use it

2019-07-09T21:38:50+00:00

This patch adds a function to check if flow block callback is already in
use.  Call this new function from flow_block_cb_setup_simple() and from
drivers.

drivers: net: use flow block API

2019-07-09T21:38:50+00:00

This patch updates flow_block_cb_setup_simple() to use the flow block API.
Several drivers are also adjusted to use it.

This patch introduces the per-driver list of flow blocks to account for
blocks that are already in use.

Remove tc_block_offload alias.

net: dsa: use switchdev handle helpers

2019-06-15T03:20:07+00:00

Get rid of the dsa_slave_switchdev_port_{attr_set,obj}_event functions
in favor of the switchdev_handle_port_{attr_set,obj_add,obj_del}
helpers which recurse into the lower devices of the target interface.

This has the benefit of being aware of the operations made on the
bridge device itself, where orig_dev is the bridge, and dev is the
slave. This can be used later to configure the hardware switches.

Only VLAN and (port) MDB objects not directly targeting the slave
device are unsupported at the moment, so skip this case in their
respective case statements.

net: dsa: make dsa_slave_dev_check use const

2019-06-15T03:20:07+00:00

The switchdev handle helpers make use of a device checking helper
requiring a const net_device. Make dsa_slave_dev_check compliant
to this.
