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]
