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:

[DEVICE [DEVICE ...]]
Utility to bind and unbind devices from Linux kernel
positional arguments:
DEVICE Device specified as PCI "domain:bus:slot.func" syntax
or "bus:slot.func" syntax. For devices bound to Linux
kernel drivers, they may be referred to by interface
name.
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}
Print the status of given device group.
-b DRIVER, --bind DRIVER
Select the driver to use or "none" to unbind the
device
-u, --unbind Unbind a device (equivalent to "-b none")
--force Override restriction on binding devices in use by
Linux" WARNING: This can lead to loss of network
connection and should be used with caution.
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
