Eli Cohen 417608c20a IB/mlx4: Remove limitation on LSO header size ...

Current code has a limitation: an LSO header is not allowed to cross a
64 byte boundary.  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.
