bridge: del external_learned fdbs from device on flush or ageout

2015-06-16T00:08:49+00:00

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.

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

2015-06-04T06:47:23+00:00

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.

switchdev: bring documentation up-to-date

2015-05-12T22:43:56+00:00

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 support

2014-12-03T04:01:20+00:00

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.
