0ab9cd9a4b rocker: forbid to change world type 
Port to world assignment should be permitted only by qemu user. Driver
should not be able to do it, so forbid that possibility.

fafa4d508b qmp/hmp: add rocker device support 
Add QMP/HMP support for rocker devices.  This is mostly for debugging purposes
to see inside the device's tables and port configurations.  Some examples:

773495364f rocker: Add support for phys name 
Add ROCKER_TLV_CMD_PORT_SETTINGS_PHYS_NAME to port settings. This attribute
exports the port name to the guest OS allowing it to name interfaces with
sensible defaults.

Mostly done by Scott for phys_id support; adapted to phys_name by David.

dc488f8880 rocker: add new rocker switch device 
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>.

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.
