net/mlx5: Fix FW tracer timestamp calculation
Fix a bug in calculation of FW tracer timestamp. Decreasing one in the calculation should effect only bits 52_7 and not effect bits 6_0 of the timestamp, otherwise bits 6_0 are always set in this calculation. Fixes: 70dd6fdb8987 ("net/mlx5: FW tracer, parse traces and kernel tracing support") Signed-off-by: Moshe Shemesh <moshe@nvidia.com> Reviewed-by: Feras Daoud <ferasda@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com>
