> Subject: [EXTERNAL] [RFC] bus/vmbus: make driver interface internal
>
> The vmbus bus API was exposed as public API, but it is only usable by the
> netvsc PMD and DPDK core: the functions operate on vmbus channels and
> devices that no application can obtain. Exposing them commits DPDK to an
> ABI that has no external consumer.
>
> Make the interface internal as announced. The public headers
> rte_bus_vmbus.h and rte_vmbus_reg.h are renamed to vmbus_api.h and
> vmbus_reg.h and listed as driver SDK headers, so they are no longer installed
> for applications. All rte_vmbus_* functions are marked __rte_internal and
> exported as internal symbols.
>
> rte_vmbus_chan_dump() had no export annotation at all, so it was declared in
> the public header but never present in the shared library.
> It is now exported as internal like the rest.
>
> netvsc needs no change: it already includes bus_vmbus_driver.h, and the bus
> driver dependency puts the driver directory on its include path.
