[openib-general] [RFC] userspace IB SA support

[Sean Hefty]

Today, userspace support for SA related operations is limited to the libibmad
interface, which supports sending and receiving MADs only.  I've been assigned
with the task of exposing multicast and informinfo support to userspace.
Specifically, the following functionality is needed:

1. Join a multicast group - needs to use the ib_sa multicast capability.
2. Receive notification of multicast errors.
3. Leave a multicast group.
4. Register to receive SA events - needs to use the ib_sa notice capability.
5. Receive notification of events.
6. Deregister from SA events.

Are there any preferences for how this is added?
