Duplicated with ntrdma/ntrdma#17

@allenbh

The rdma-core package replaces various (lib)ibverbs and (lib)rdmacm packages.
Part of the change, <infiniband/driver.h> is no longer shipped even in devel packages.

So what should be the future of https://github.com/ntrdma/ntrdma-lib ?
Should it be merged to https://github.com/linux-rdma/rdma-core ?

What do you think should happen here?

Thanks,

Yes, it should be made to build with rdma-core, and updated for changes in the current driver interface.

Thanks. Few more questions:

  1. Should ntrdma-lib still remain as a separate git project or PR to push it to rdma-core project?
  2. Should same branches here as in rdma-core (stable-v15, stable-v16, stable-v17, stable-v18, stable-v19, stable-v20, stable-v21,...) be created in ntrdma-lib in order to support different stable branches of rdma-core or just master is enough?

In my opinion, if libntrdma was replaced by a generic user space library that uses system calls for all verbs, that would be better, and possibly also useful for other drivers. That is all libntrdma does, except that it recognises devices named ntrdma.

Sounds interesting... Will think about that...
