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.

qapi: Change Netdev into a flat union
This is a mostly-mechanical conversion that creates a new flat
union 'Netdev' QAPI type that covers all the branches of the
former 'NetClientOptions' simple union, where the branches are
now listed in a new 'NetClientDriver' enum rather than generated
from the simple union. The existence of a flat union has no
change to the command line syntax accepted for new code, and
will make it possible for a future patch to switch the QMP
command to parse a boxed union for no change to valid QMP; but
it does have some ripple effect on the C code when dealing with
the new types.
While making the conversion, note that the 'NetLegacy' type
remains unchanged: it applies only to legacy command line options,
and will not be ported to QMP, so it should remain a wrapper
around a simple union; to avoid confusion, the type named
'NetClientOptions' is now gone, and we introduce 'NetLegacyOptions'
in its place. Then, in the C code, we convert from NetLegacy to
Netdev as soon as possible, so that the bulk of the net stack
only has to deal with one QAPI type, not two. Note that since
the old legacy code always rejected 'hubport', we can just omit
that branch from the new 'NetLegacyOptions' simple union.
Based on an idea originally by Zoltán Kővágó <DirtY.iCE.hu@gmail.com>:

although the sed script in that patch no longer applies due to
other changes in the tree since then, and I also did some manual
cleanups (such as fixing whitespace to keep checkpatch happy).

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.
