Has this been run by the networking community? Are they OK with this

I did copy netdev on the original submissions, but I don't remember any explicit ack or nack.

David, any feeling yay or nay about adding these?
Is the kernel the final arbiter of AF_xxx / PF_xxx assignments, or
is there anything else we have to worry about?
Thanks,
Roland

To clarify the intent of this change:
The RDMA CM allows users to specify addresses using struct sockaddr. Today, only INET/6 are supported. The intent is to allow a user to specify native InfiniBand addresses through that interface. In the more immediate, this helps to solve InfiniBand scaling issues. Longer term, this can also be used to control path failover.

Yes, this is key for InfiniBand scaling.

This AF_IB patch series appears to be stalled unless I missed something
on the list. What needs to be done to revive it/move it along ?
Thanks.
