Hi Hemminger,

Latest "dpdk-devbind.py --status-dev" just can support  {net,baseband,crypto,event,mempool,compress} devices, 
But can not support show Misc devices, can you fix it or provide new method to show?

Notes: Old dpdk-devbind.py can support show cbdma device by cmd " ./usertools/dpdk-devbind.py --status-dev misc "

Trace Log:
	root@dpdk-yaobing-purely147:~/dpdk# ./usertools/dpdk-devbind.py --status-dev misc
	usage: dpdk-devbind.py [-h] [-s]
                       [--status-dev {net,baseband,crypto,event,mempool,compress}]
                       [-b DRIVER | -u] [--force]
                       [DEVICE [DEVICE ...]]
	dpdk-devbind.py: error: argument --status-dev: invalid choice: 'misc' (choose from 'net', 'baseband', 'crypto', 'event', 'mempool', 'compress')

optional arguments:
  -h, --help            show this help message and exit
  -s, --status          Print the current status of all known devices.
  --status-dev {net,baseband,crypto,event,mempool,compress}

Examples:
---------

To display current device status:
        dpdk-devbind.py --status

To display current network device status:
        dpdk-devbind.py --status-dev net

To bind eth1 from the current driver and move to use vfio-pci
        dpdk-devbind.py --bind=vfio-pci eth1

To unbind 0000:01:00.0 from using any driver
        dpdk-devbind.py -u 0000:01:00.0

To bind 0000:02:00.0 and 0000:02:00.1 to the ixgbe kernel driver
        dpdk-devbind.py -b ixgbe 02:00.0 02:00.1
