* bridge: del external_learned fdbs from device on flush or ageoutScott Feldman2015-06-161-9/+2Star
| | | | | | | | | | | | | | | | | | | | | | | | 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 <sfeldma@gmail.com> Signed-off-by: David S.

* switchdev: documentation: use switchdev_port_obj_xxx for IPv4 FIB ↵Scott Feldman2015-06-041-24/+29
| | | | | | | | | | | | | | | add/modify/delete ops 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.

| | | | | | | | There were a few review comments on the switchdev.txt documentation that didn't get included with the Spring Cleanup series, so include them now. Signed-off-by: Scott Feldman <sfeldma@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* switchdev: bring documentation up-to-dateScott Feldman2015-05-131-59/+355
| | | | | | | | | | | 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.

* net: introduce generic switch devices supportJiri Pirko2014-12-031-0/+59
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.
