Jakub, David

Can we please ask that everything directly or indirectly related to RDMA
will be sent to linux-rdma@ too?

In addition to all that was discussed regarding qed_rdma.c 
and qed_rdma_ops - certainly, everything directly or indirectly 
related to RDMA will be sent to linux-rdma.

Maybe it is only description that needs to be updated, but I would
expect to see call to pcie_relaxed_ordering_enabled() before setting
relaxed_ordering to always true.

This change will only allow the FW to support relaxed ordering but it 
will be enabled only if the device/root-complex/server supports 
relaxed ordering.
The pcie_relaxed_ordering_enabled() is not needed in this case.

If we are talking about RDMA, the IB_ACCESS_RELAXED_ORDERING flag should
be taken into account too.

Thanks! 
We will need to add both FW and driver support to enable it.

Thanks
