Rocker is a simulated ethernet switch device. The device supports up to 62 front-panel ports and supports L2 switching and L3 routing functions, as well as L2/L3/L4 ACLs. The device presents a single PCI device for each switch, with a memory-mapped register space for device driver access. Rocker device is invoked with -device, for example a 4-port switch: -device rocker,name=sw1,len-ports=4,ports[0]=dev0,ports[1]=dev1, \ ports[2]=dev2,ports[3]=dev3 Each port is a netdev and can be paired with using -netdev id=<port name>.

Signed-off-by: David Ahern <dsahern@gmail.com> Acked-by: Scott Feldman <sfeldma@gmail.com> Acked-by: Jiri Pirko <jiri@resnulli.us> rocker: add support for flow modification We had support for flow add/del. This adds support for flow mod. I needed this for L3 support where an existing route is modified using NLM_F_REPLACE. For example: ip route add 12.0.0.0/30 nexthop via 11.0.0.1 dev swp1 ip route change 12.0.0.0/30 nexthop via 11.0.0.9 dev swp2 The first cmd adds the route. The second cmd changes the existing route by changing its nexthop info. In the device, a mod operation results in the matching flow enty being modified with the new settings. This is atomic to the device. Signed-off-by: Scott Feldman <sfeldma@gmail.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
