Marc-André Lureau dd054be35f config: enable ivshmem on POSIX
ivshmem doesn't actually require kvm, so enable it when POSIX is
enabled. (it is required however when ioeventfd is enabled)

Scott Feldman 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.

David Gibson 8af738b3ee Give ivshmem its own config option
Currently the ivshmem device is built whenever both PCI and KVM support are
included.  This patch gives it its own config option to allow easier
customization of whether to include it.  It's enabled by default in the
same circumstances as now - when both PCI and KVM are available.

Keith Busch f3c507adcd NVMe: Initial commit for new storage interface
Initial commit for emulated Non-Volatile-Memory Express (NVMe) pci
storage device.

NVMe is an open, industry driven storage specification defining
an optimized register and command set designed to deliver the full
capabilities of non-volatile memory on PCIe SSDs. Further information
may be found on the organizations website at:

http://www.nvmexpress.org/

This commit implements the minimum from the specification to work with
existing drivers.

Hector Martin 62c6ae04cf xhci: Initial xHCI implementation
Based on the implementation from Hector Martin <hector@marcansoft.com>

Hectors's implementation completely sidestepped the qemu usb system and
used libusb directly for usb device pass through.  So I've ripped out
the libusb bits (or left them in disabled, as reference for further
coding) and hooked up the qemu subsystem instead.  That work is not
complete yet though, partly due to limitations of the qemu usb
subsystem.  Nevertheless I think it is better to continue development
in-tree, especially as the qemu usb bits need a bunch of improvements
too for decent usb 3.0 support.

Current state:
  - usb-storage emulation should work ok.
  - Devices which need constant polling (HID emulation like usb-tablet)
    are known to not work.
  - ISO xfers are not implemented yet.
  - superspeed ports are not implemented yet.
  - usb pass-through is completely untested so far.
