[PATCH v2 0/9] NTB: Alter kernel API to support multi-port devices

From: Serge Semin
Date: Mon Dec 12 2016 - 16:09:15 EST


There are devices, like IDT PCIe-switches, which have more than just two ports.
Particularly one device can have up to eight ports with NTB-function activated.
In order to support such devices, NTB kernel API should be altered since
currently it's optimized to work with two-ports devices only.

Changelog v2:
- Move comments from cover letter to individual patches
- Combine patches to make code buildable
- Alter patchset to support Intel SKX driver
- Make sure all the API uses the same midx/widx/pidx/sidx arguments notation
- Move new MW API usage description into Documention
- Alter Spad/Msg API checking valid function to make spad and msg interfaces optional
- Alter comments in ntb.h
- Split: add NTB_SPEED_GEN4 and ntb.h comments into separate patches
- Put copyrights into some of the existing patches
- Get rid of TOPO updates
