This patch removes this limitation by setting the WQE RR for large headers thus allowing LSO headers of any size. The extra buffer reserved for MLX4_IB_QP_LSO QPs has been doubled, from 64 to 128 bytes, assuming this is reasonable upper limit for header length. Also, this patch will cause IB_DEVICE_UD_TSO to be set only for HCA FW versions that set MLX4_DEV_CAP_FLAG_BLH; e.g. FW version 2.6.000 and higher.
