libibverbs-1.2.0-rc1 release

I have done a pre-release of the upcoming libibverbs-1.2.0 release. The code has been pushed to the official git repo and also an -rc1 tarball uploaded to the https://ww.openfabrics.org/downloads/verbs download area. From the tag message:

tag libibverbs-1.2.0-rc1

Ininitial roundup of 1.2.0 release items

- Add support for RoCE
- Add support for On Demand Paging
- No longer assume that no driver for a verbs device should be considered an error condition (usnic devices in particular are moving to libfabric drivers only, so we will emit a useless warning/error in the presence of usnic enabled machines)
- Harden some of the argument processing in example programs
- Add support for s390x
- Fix the broken create/destroy flow API
- First release under new management (hence the decision to update to version 1.2.0 instead of 1.1.9)

In particular, as this release fixes the create/destroy flow API, there is a need for an updated libmlx4 sources in order to compile against the fixed API (binary compatibility was maintained, but source compatibility was not, so you will need the new libmlx4 to compile against the new libibverbs). Yishai, please post an updated libmlx4 head of repo and preferably also a source tarball for libmlx4 when it's ready. Preferably it would include an embedded check for the proper flow API in your configure scripts.

Doug, so when is this release expected to happen? the last release took place in 2014.

Yishai, are you expecting anything to be added to libmlx4 for your upcoming release?
if not, I guess you can sign it already against 1.2.0-rc1, right?

Or.

Doug, please be aware that currently there is a problem to build an rpm from the libibverbs git repository.

Major version number can't have hyphen "-". (e.g. "-rc1").
Also, version should be updated in libibverbs.spec.in.
You can use latest commits to libmlx4 as some reference for correct usage. (i.e. http://git.openfabrics.org/?p=~yishaih/libmlx4.git;a=summary).

No, the official libmlx4 git-repository is-up-to-date with the candidate stuff.

When there will be a formal release of libibverbs after fixing above issue, I'll build a matching libmlx4 tar ball.
