mlx4: Add blue flame support for kernel consumers
Using blue flame can improve latency by allowing the HW to more efficiently access the WQE. This patch presents two functions that are used to allocate or release HW resources for using blue flame; the caller need to supply a struct mlx4_bf object when allocating resources. Consumers that make use of this API should post doorbells to the UAR object pointed by the initialized struct mlx4_bf; Signed-off-by: Eli Cohen <eli@mellanox.co.il> Signed-off-by: David S.
