[dpdk-dev] Does FreeBSD's nic_uio have bind/unbind interface support?

Hi All,
It seems that on FreeBSD, nic_uio currently only binds the devices matched in
rte_pci_dev_ids.h. On Linux, it's possible to bind any listed device with
igb_uio or vfio.
The pci device ids supported by cxgbe PMD, maintained in a table, are not part
of rte_pci_dev_ids.h. Hence, Chelsio T5 cards don't get bound to nic_uio,
resulting in probe failure on FreeBSD.
On manually adding Chelsio pci device id to rte_pci_dev_ids.h, the Chelsio T5
card gets detected fine on FreeBSD.
So, we would like to know and understand if adding all supported Chelsio pci
device ids to rte_pci_dev_ids.h is the correct way of doing things for FreeBSD?
Any suggestions are appreciated.
Thanks,
Rahul
