* rocker: Remove support bridge bypass FDBArkadi Sharshevsky2017-06-081-3/+0
| | | | | | | | | The FDB add/delete are now done through the notification chain. The FDBs are synced with the bridge and there is no need for extra dumping.

* rocker: Remove support for bypass bridge port attributes/vlan setArkadi Sharshevsky2017-06-081-3/+0
| | | | | | | | | | The bridge port attributes/vlan for mlxsw devices should be set only from bridge code. The vlans are synced totally with the bridge so there is no need to special dump support.

| | | | | | | | | | Currently the switchdev_trans struct is embedded in the world_ops API. In order to add support for adding FDB via a notfication chain the API should be switchdev independent.

* rocker: Create an ordered workqueue for FIB offloadIdo Schimmel2016-12-041-0/+1
| | | | | | | | | | | | | As explained in the previous commits, we need to process FIB entries addition / deletion events in FIFO order or otherwise we can have a mismatch between the kernel's FIB table and the device's. Create an ordered workqueue for rocker to which these work items will be submitted to.

* rocker: use FIB notifications instead of switchdev callsJiri Pirko2016-09-281-5/+10
| | | | | | | | | | Until now, in order to offload a FIB entry to HW we use switchdev op. Use the newly introduced FIB notifier infrasturucture to process FIB entries to offload the in HW. Abort mechanism is now handled within the rocker driver. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* rocker: move ageing_time from struct rocker to struct ofdpaJiri Pirko2016-03-131-1/+0
| | | | | | | | This is OF-DPA specific, used only there, similar to ofdpa_port->ageing_time. So move it to OF-DPA code. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* rocker: set FDB cleanup timer according to lowest ageing timeIdo Schimmel2016-03-111-0/+1
| | | | | | | | | | | | | In rocker, ageing time is a per-port attribute, so the next time the FDB cleanup timer fires should be set according to the lowest ageing time. This will later allow us to delete the BR_MIN_AGEING_TIME macro, which was added to guarantee minimum ageing time in the bridge layer, thereby breaking existing behavior.

* rocker: move OF-DPA stuff into separate fileJiri Pirko2016-02-181-38/+15
| | | | | | | | | | | Carve out OF-DPA would specific code from the common file to the world file. This change required struct rocker and struct rocker_port split into world specific struct ofdpa and struct ofdpa_port. Along with this the world specific functions and defines were renamed from prefix "rocker_" to "ofdpa_". Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* rocker: introduce worlds infrastructureJiri Pirko2016-02-181-0/+69
| | | | | | | | | This is another step on the way to per-world clean cut. Introduce world ops hooks which each world can implement in world-specific way. Also introduce world infrastructure along with OF-DPA world stub. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* rocker: move rocker and rocker_port structs into headerJiri Pirko2016-02-181-0/+75

* rocker: add offload_fwd_mark supportScott Feldman2015-07-211-0/+1
| | | | | | | | | | | | | | | If device flags ingress packet as "fwd offload", mark the skb->offlaod_fwd_mark using the ingress port's dev->offlaod_fwd_mark. This will be the hint to the kernel that this packet has already been forwarded by device to egress ports matching skb->offlaod_fwd_mark. For rocker, derive port dev->offlaod_fwd_mark based on device switch ID and port ifindex. If port is bridged, use the bridge ifindex rather than the port ifindex.

* rocker: add support for phys_port_nameDavid Ahern2015-03-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | Implement the phys_port_name operation. Port names are pulled from the rocker hardware model in qemu and default to the qemu name + port id. e.g., sw1p1: flags=4098<BROADCAST,MULTICAST> mtu 1500 ether 52:54:00:12:35:01 txqueuelen 1000 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 where 'sw1' comes from the qemu command line -device rocker,name=sw1, and 'p1' is port 1. Patch is adapted from Scott's phys_port_id patch.

* rocker: rename lport to pportScott Feldman2015-02-261-8/+8
| | | | | | | | | | | This is just a rename of physical ports from "lport" to "pport". Not a functional change. OF-DPA uses logical ports (lport) for tunnels, but the driver (and device) were using "lport" for physical ports. Renaming physical ports references to "pport", freeing up "lport" for use later with tunnels.

* rocker: fix non-portable err return codesScott Feldman2015-02-261-0/+13
| | | | | | | | | | | | The rocker device returns error codes if something goes wrong with descriptor processing. Originally the device used standard errno codes for different errors, but since those errno codes aren't portable across ARCHs, the device now returns hard-coded error codes that stay constant across diff ARCHs. Fix driver to use those same hard-coded values. Signed-off-by: Scott Feldman <sfeldma@gmail.com> Acked-by: Jiri Pirko <jiri@resnulli.us> Signed-off-by: David S. Miller <davem@davemloft.net>

* rocker: introduce rocker switch driverJiri Pirko2014-12-031-0/+427
This patch introduces the first driver to benefit from the switchdev infrastructure and to implement newly introduced switch ndos. This is a driver for emulated switch chip implemented in qemu: https://github.com/sfeldma/qemu-rocker/ This patch is a result of joint work with Scott Feldman.
