switchdev: Adding MDB entry offload

2016-01-10T21:50:20Z

Define HW multicast entry: MAC and VID. Using a MAC address simplifies support for both IPV4 and IPv6. Signed-off-by: Elad Raz Signed-off-by: Ido Schimmel Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

switchdev: add bridge vlan_filtering attribute

2016-01-06T19:42:40Z

Adding vlan_filtering attribute to allow hardware vendor to support vlan-aware bridges. Vlan_filtering is a per-bridge attribute. Signed-off-by: Elad Raz Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

switchdev: Pass original device to port netdev driver

2015-12-15T16:58:20Z

switchdev drivers need to know the netdev on which the switchdev op was invoked. For example, the STP state of a VLAN interface configured on top of a port can change while being member in a bridge. In this case, the underlying driver should only change the STP state of that particular VLAN and not of all the VLANs configured on the port. However, current switchdev infrastructure only passes the port netdev down to the driver. Solve that by passing the original device down to the driver as part of the required switchdev object / attribute. This doesn't entail any change in current switchdev drivers. It simply enables those supporting stacked devices to know the originating device and act accordingly. Signed-off-by: Ido Schimmel Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

net: switchdev: fix return code of fdb_dump stub

2015-11-16T20:24:37Z

rtnl_fdb_dump always expects an index to be returned by the ndo_fdb_dump op, but when CONFIG_NET_SWITCHDEV is off, it returns an error. Fix that by returning the given unmodified idx. A similar fix was 0890cf6cb6ab ("switchdev: fix return value of switchdev_port_fdb_dump in case of error") but for the CONFIG_NET_SWITCHDEV=y case. Fixes: 45d4122ca7cd ("switchdev: add support for fdb add/del/dump via switchdev_port_obj ops.") Signed-off-by: Dragos Tatulea Acked-by: Jiri Pirko Signed-off-by: David S. Miller

switchdev: introduce possibility to defer obj_add/del

2015-10-15T13:09:49Z

Similar to the attr usecase, the caller knows if he is holding RTNL and is in atomic section. So let the called to decide the correct call variant. This allows drivers to sleep inside their ops and wait for hw to get the operation status. Then the status is propagated into switchdev core. This avoids silent errors in drivers.

switchdev: remove pointers from switchdev objects

2015-10-15T13:09:49Z

When object is used in deferred work, we cannot use pointers in switchdev object structures because the memory they point at may be already used by someone else. So rather do local copy of the value.

switchdev: allow caller to explicitly request attr_set as deferred

2015-10-15T13:09:48Z

Caller should know if he can call attr_set directly (when holding RTNL) or if he has to defer the att_set processing for later. This also allows drivers to sleep inside attr_set and report operation status back to switchdev core. Switchdev core then warns if status is not ok, instead of silent errors happening in drivers. Benefit from newly introduced switchdev deferred ops infrastructure. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

switchdev: introduce switchdev deferred ops infrastructure

2015-10-15T13:09:46Z

Introduce infrastructure which will be used internally to defer ops. Note that the deferred ops are queued up and either are processed by scheduled work or explicitly by user calling deferred_process function. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

switchdev: skip over ports returning -EOPNOTSUPP when recursing ports

2015-10-12T12:20:20Z

This allows us to recurse over all the ports, skipping over unsupporting ports. Without the change, the recursion would stop at first unsupported port. Signed-off-by: Scott Feldman Acked-by: Jiri Pirko Signed-off-by: David S. Miller
