The fourth edition of SMCv2 adds the SMC version 2.1 feature updates for
SMC-Dv2 with virtual ISM. Virtual ISM are created and supported mainly by
OS or hypervisor software, comparable to IBM ISM which is based on platform
firmware or hardware.
With the introduction of virtual ISM, SMCv2.1 makes some updates:
- Introduce feature bitmask to indicate supplemental features.
- Reserve a range of CHIDs for virtual ISM.
- Support extended GIDs (128 bits) in CLC handshake.
So this patch set aims to implement these updates in Linux kernel. And it
acts as the first part of the new version of [1].

Hi Wen Gu,
Just FYI, the review is still on going and some tests on our plateform
still need to do. I'll give you my comments as soon as the testing is
done. I think it would be at the beginning of next week.
Thanks,
Wenjia
