Instead of modifying the value member of a list element passed as a
parameter, and open-coding the manipulation of that list, it's nicer
to just return a freshly allocated value to be prepended to a list
using QAPI_LIST_PREPEND.

Port to world assignment should be permitted only by qemu user. Driver
should not be able to do it, so forbid that possibility.

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.

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.
