Hi,
when the mlx4 FW generate an internal error, the driver's catas code tries to
reset the HCA and restart the stack. However if the CM is in use at that moment,
the stack shutdown never completes and hangs in the CM waiting for a refcount
that never reaches 0.

In mlx4_ib_reg_xrc_rcv_qp(), we need to take the xrc_reg_list_lock spinlock
when walking the xrc_reg_list.
We've been hit by this on 2 customer sites.
Also, I guess spin_lock_irqsave() could be replaced by spin_lock_irq() in
that function as we know for sure we're in process context.

I believe that datagram mode can bring you to or closely

a single IB link that then gets routed through 2 ethernet links.

Hi,
I know this might be off topic, but somebody may have already run into the
same
problem before.
I'm trying to use a server as a router between an IB fabric and an Ethernet
network.
The router is fitted with one ConnectX2 QDR HCA and one dual port Myricom 10G
Ethernet adapter.
. Are there any real world figures out there
concerning the 4036E performance?
Thanks Richard,
Sébastien.

The ib_umad_port's sm_sem semaphore is initialized as a mutex which
although it builds (with a warning) badly breaks at runtime.
Fix this by using the proper initialization function sema_init().
Also fix those DOSish end of lines.

I agree. If setting QoS requires a kernel patch
These patches allow to have a specific QoS for Lustre traffic.
- Patch 1 adds a new Lustre port space to the rdma_cm kernel module
- Patch 2 defines a new Lustre service ID (matching the new RDMA CMA port
space) and a new 'lustre' keyword in the OpenSM QoS policy parser.
