Patch 1~5: move vdev bus into drivers/bus.
Patch 6: add unix socket channel for primary/secondary communication.
Patch 7~8: make use of the channel to discover and probe virtual devices
         the primary process.
Patch 9~12: support to run vhost-pmd in the secondary process.

How to test:

Step 1: run helloworld as the primary process.
  $ ./helloworld -l 1-2 --vdev 'net_vhost0,iface=/tmp/sock0' --

Step 2: run testpmd as the secondary process.
  $ ./testpmd -l 3-4 --proc-type=secondary -- -i

Step 3: start VM.
  $ ./qemu-system-x86_64 ... -chardev socket,id=chr4,path=/tmp/sock0 ...

Jianfeng Tan (12):
  cryptodev: remove crypto vdev init
  eal: avoid calling rte_vdev_init()
  crypto: move vdev helper functions into dedicated file
  vdev: move to drivers/bus
  bus/vdev: change log type from EAL to PMD
  eal: add channel for primary/secondary communication
  bus/vdev: scan and probe vdev in secondary processes
  ethdev: support attach vdev in secondary process
  vhost: allocate virtio_net in memzone
  vhost: support to kick in secondary process
  net/vhost: support to run in the secondary process
  examples/helloworld: do not exit automatically
