What if people want to experiment with other bit mask settings? They can't do that if you don't document the layout fully and properly. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

At the moment VFs can only operate in Eth mode. In addition we don't want the VF to attempt link sensing, so we block this option as well. Signed-off-by: Yevgeny Petrilin <yevgenyp@mellanox.co.il> --- drivers/net/ethernet/mellanox/mlx4/fw.c | 6 ++++-- 1 files changed, 4 insertions(+), 2 deletions(-)
