rocker: hook ndo_neigh_destroy to cleanup neigh refs in driver

2015-08-14T00:05:46Z

Rocker driver tracks arp_tbl neighs to resolve IPv4 route nexthops. The driver uses NETEVENT_NEIGH_UPDATE for neigh adds and updates, but there is no event when the neigh is removed from the device (such as when the device goes admin down). This patches hooks ndo_neigh_destroy so the driver can know when a neigh is removed from the device. In response, the driver will purge the neigh entry from its internal tbl. I didn't find an in-tree users of ndo_neigh_destroy, so I'm not sure if this ndo is vestigial or if there are out-of-tree users. In any case, it does what I need here. An alternative design would be to generate NETEVENT_NEIGH_UPDATE event when neigh is being destroyed, setting state to NUD_NONE so driver knows neigh entry is dead.

bridge: del external_learned fdbs from device on flush or ageout

2015-06-16T00:08:49Z

We need to delete from offload the device externally learnded fdbs when any one of these events happen: 1) Bridge ages out fdb. (When bridge is doing ageing vs. device doing ageing. If device is doing ageing, it would send SWITCHDEV_FDB_DEL directly). 2) STP state change flushes fdbs on port. 3) User uses sysfs interface to flush fdbs from bridge or bridge port: echo 1 >/sys/class/net/BR_DEV/bridge/flush echo 1 >/sys/class/net/BR_PORT/brport/flush 4) Offload driver send event SWITCHDEV_FDB_DEL to delete fdb entry. For rocker, we can now get called to delete fdb entry in wait and nowait contexts, so set NOWAIT flag when deleting fdb entry. Signed-off-by: Scott Feldman Signed-off-by: David S. Miller

switchdev: documentation: use switchdev_port_obj_xxx for IPv4 FIB add/modify/delete ops

2015-06-04T06:47:23Z

Clarify in documentation and code that IPV4 FIB add operation is used for both adding a new FIB entry to the device and for modifying an existing FIB entry on the device. Also, remove left-over references to ipv4_fib ops and replace with details on SWITCHDEV_PORT_IPV4_FIB object. Signed-off-by: Scott Feldman Acked-by: Jiri Pirko Signed-off-by: David S. Miller

switchdev: bring documentation up-to-date

2015-05-12T22:43:56Z

Much need updated of switchdev documentation to cover what's been implmented to-date. There are some XXX comments in the text for unimplemented or broken items. I'd like to keep these in there (poor-man's TODO list) and update the document once each issue is resolved. Signed-off-by: Scott Feldman Acked-by: Jiri Pirko Signed-off-by: David S. Miller

net: introduce generic switch devices support

2014-12-03T04:01:20Z

The goal of this is to provide a possibility to support various switch chips. Drivers should implement relevant ndos to do so. Now there is only one ndo defined: - for getting physical switch id is in place. Note that user can use random port netdevice to access the switch.
