Subject: [PATCH 10/25] mlx4_core: track slave special qps
Date: Wednesday, November 4, 2009 - 8:31 am

A single function can own the actual Infiniband hw special qps.
This function demuxes inbound mads and protects outbound mads from spoofing.
To achieve this, it needs to know the special qps used by other functions.

This patch tracks special qp registration and notifies the owning function
on any changes.
