												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.
