2015-03-20switchdev: kernel-doc cleanup on swithdev opsScott Feldman1-16/+7
Suggested-by: Ben Hutchings <ben@decadent.org.uk> Signed-off-by: Scott Feldman <sfeldma@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-03-16switchdev: add swdev opsScott Feldman1-0/+38
As discussed at netconf, introduce swdev_ops as first step to move switchdev ops from ndo to swdev. This will keep switchdev from cluttering up ndo ops space. Signed-off-by: Scott Feldman <sfeldma@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-03-09switchdev: add netlink flags to IPv4 FIB add opScott Feldman1-2/+4
Pass in the netlink flags (NLM_F_*) into switchdev driver for IPv4 FIB add op to allow driver to 1) optimize hardware updates, 2) handle ip route prepend and append commands correctly.

2015-03-06fib: make netdev_switch_fib_ipv4_abort in header file static inlineWillem de Bruijn1-1/+1
When building without CONFIG_NET_SWITCHDEV, netdev_switch_fib_ipv4_abort is defined in the header file. It must be static inline to avoid build failure at link time.

2015-03-06fib: hook IPv4 fib for hardware offloadScott Feldman1-0/+5
Call into the switchdev driver any time an IPv4 fib entry is added/modified/deleted from the kernel's FIB. The switchdev driver may or may not install the route to the offload device. In the case where the driver tries to install the route and something goes wrong (device's routing table is full, etc), then all of the offloaded routes will be flushed from the device, route forwarding falls back to the kernel, and no more routes are offloading. We can refine this logic later. For now, use the simplist model of offloading routes up to the point of failure, and then on failure, undo everything and mark IPv4 offloading disabled.

Add IPv4 fib ndo wrapper funcs and stub them out for now. Signed-off-by: Scott Feldman <sfeldma@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-02-01swdevice: add new apis to set and del bridge port attributesRoopa Prabhu1-1/+36
This patch adds two new api's netdev_switch_port_bridge_setlink and netdev_switch_port_bridge_dellink to offload bridge port attributes to switch port (The names of the apis look odd with 'switch_port_bridge', but am more inclined to change the prefix of the api to something else. Will take any suggestions). The api's look at the NETIF_F_HW_SWITCH_OFFLOAD feature flag to pass bridge port attributes to the port device.

2015-01-18net: replace br_fdb_external_learn_* calls with switchdev notifier eventsJiri Pirko1-0/+11
This patch benefits from newly introduced switchdev notifier and uses it to propagate fdb learn events from rocker driver to bridge. That avoids direct function calls and possible use by other listeners (ovs).

2015-01-18switchdev: introduce switchdev notifierJiri Pirko1-0/+31
This patch introduces new notifier for purposes of exposing events which happen on switch driver side. The consumers of the event messages are mainly involved masters, namely bridge and ovs. Suggested-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: Jiri Pirko <jiri@resnulli.us> Signed-off-by: Scott Feldman <sfeldma@gmail.com> Signed-off-by: David S.

2014-12-02net: introduce generic switch devices supportJiri Pirko1-0/+30
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.
