From Jake: Vendor drivers that exist out-of-tree generally should return BUS_PROBE_VENDOR from their device probe functions. This helps ensure that a vendor replacement driver will supersede the in-kernel driver for a given device. Currently, if a vendor wants to implement a driver based on iflib, it will always report BUS_PROBE_DEFAULT. Add a wrapper function, iflib_device_probe_vendor() which can be used in place of iflib_device_probe(). This function will just return BUS_PROBE_VENDOR whenever iflib_device_probe() would return BUS_PROBE_DEFAULT. While vendor drivers can already implement such a wrapper themselves, providing it in the iflib.h header makes it easier for the vendor driver to do the right thing.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
