[PATCH v3 00/15] NTB: Add full multi-port API support to the test drivers

[Serge Semin]

The multi-port NTB API was introduced in kernel 4.13 as well as the
first driver for the true multi-port devices of IDT PCIe-switches
series. But the test drivers still were left almost unchanged. Yes,
they didn't fail being used with new NTB API, but they only worked
with two-ports NTB devices. This patchset is intended to fix the
issue by amending the NTB test drivers and script so they would be
fully compatible with multi-port NTB API.

Additionally I found a few NTB subsystem issues while developing the
submitted patches. So they are also fixed in this patchset.
