net: switchdev: Remove bridge bypass support from switchdev

2017-08-07T21:48:48Z

Currently the bridge port flags, vlans, FDBs and MDBs can be offloaded through the bridge code, making the switchdev's SELF bridge bypass implementation to be redundant. This implies several changes: - No need for dump infra in switchdev, DSA's special case is handled privately. - Remove obj_dump from switchdev_ops. - FDBs are removed from obj_add/del routines, due to the fact that they are offloaded through the bridge notification chain. - The switchdev_port_bridge_xx() and switchdev_port_fdb_xx() functions can be removed.

net: dsa: Move FDB dump implementation inside DSA

2017-08-07T21:48:48Z

>From all switchdev devices only DSA requires special FDB dump. This is due to lack of ability for syncing the hardware learned FDBs with the bridge. Due to this it is removed from switchdev and moved inside DSA. Signed-off-by: Arkadi Sharshevsky Signed-off-by: David S. Miller

net: switchdev: add SET_SWITCHDEV_OPS helper

2017-07-01T15:51:32Z

Add a helper to allow switchdev ops to be set if NET_SWITCHDEV is configured and do nothing otherwise. This allows for slightly cleaner code which uses switchdev but does not select NET_SWITCHDEV. Signed-off-by: Simon Horman Acked-by: Ivan Vecera Signed-off-by: David S. Miller

net: bridge: Receive notification about successful FDB offload

2017-06-08T18:16:25Z

When a new static FDB is added to the bridge a notification is sent to the driver for offload. In case of successful offload the driver should notify the bridge back, which in turn should mark the FDB as offloaded. Currently, externally learned is equivalent for being offloaded which is not correct due to the fact that FDBs which are added from user-space are also marked as externally learned. In order to specify if an FDB was successfully offloaded a new flag is introduced.

net: bridge: Add support for notifying devices about FDB add/del

2017-06-08T18:16:25Z

Currently the bridge doesn't notify the underlying devices about new FDBs learned. The FDB sync is placed on the switchdev notifier chain because devices may potentially learn FDB that are not directly related to their ports, for example: 1. Mixed SW/HW bridge - FDBs that point to the ASICs external devices should be offloaded as CPU traps in order to perform forwarding in slow path. 2. EVPN - Externally learned FDBs for the vtep device. Notification is sent only about static FDB add/del. This is done due to fact that currently this is the only scenario supported by switch drivers.

net: switchdev: Add support for querying supported bridge flags by hardware

2017-06-08T18:16:23Z

This is done as a preparation stage before setting the bridge port flags from the bridge code. Currently the device can be queried for the bridge flags state, but the querier cannot distinguish if the flag is disabled or if it is not supported at all. Thus, add new attr and a bit-mask which include information regarding the support on a per-flag basis. Drivers that support bridge offload but not support bridge flags should return zeroed bitmask.

switchdev: Fix return value of switchdev_port_fdb_dump().

2016-09-02T18:00:21Z

This patch fixes the retun value of switchdev_port_fdb_dump() when CONFIG_NET_SWITCHDEV is not set. This avoids getting "warning: return makes integer from pointer without a cast [-Wint-conversion]" when building when CONFIG_NET_SWITCHDEV is not set under several compiler versions. This warning is due to commit d297653dd6f07afbe7e6c702a4bcd7615680002e ("rtnetlink: fdb dump: optimize by saving last interface markers").
