How to hotplug a PCI device (such as VF) on FreeBSD

Hi,

I'm looking for a way to refresh the pci device list.
In Linux, we can remove a particular pci device, and then after preforming a "rescan" the device will appear again.
For example, disable/rescind PCI (such as VF) :
echo 1 >  /sys/bus/pci/devices/0001\:00\:02.0/remove
# Get the device back
echo 1 > /sys/bus/pci/rescan

I'm looking for a similar way in FreeBSD. Does the FreeBSD support the hotplug of a PCI device?  Thanks in advance!


Thanks,
Hongxiong
