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>.

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:
(qemu) info rocker sw1
name: sw1
id: 0x0000013512005452
ports: 4
(qemu) info rocker-ports sw1
ena/ speed/ auto
port link duplex neg?
sw1.1 up 10G FD No
sw1.2 up 10G FD No
sw1.3 !ena 10G FD No
sw1.4 !ena 10G FD No
(qemu) info rocker-of-dpa-flows sw1
