I want to answer MAD requests from the SM but from some point in time in my
system's flow the kernel is blocked and taken over by my own code.
When the system is setting up I use openib to create connections between the
system's nodes, but from some point in time I start writing to Mellanox hardware
directly instead of using openib calls.
To do this with qp0 too (control it directly) I need to destroy its current
instance.
