rte_eal_unbind_kernel_driver() defined in the patch is essentially a
wrapper which can be implemented for Linux as well as BSD. Just that in
this patch a ENOTSUP implementation of this was not given for BSD.
I can think of two options:
1. Implement a ENOTSUPP code for BSD and allow
rte_eal_unbind_kernel_driver() as part of common/eal_private header.
implement rte_eal_unbind_kernel_driver in BSD as not supported.
2. That we keep this contained within Linux area:
linux_unbind_kernel_driver <-- pci_unbind_kernel_driver
^
`-- xxx_unbind_kernel_driver
bsd_unbind_kernel_driver <-- pci_unbind_kernel_driver
`-> this returns ENOTSUPP
@Jan: any additions/suggestions?
