net/mlx5e: Fix number of PFC counters reported to ethtool
Number of PFC counters used to count only number of priorities with PFC enabled, but each priority has more than one counter, hence the need to multiply it by the number of PFC counters per priority. Fixes: cf678570d5a1 ('net/mlx5e: Add per priority group to PPort counters') Signed-off-by: Gal Pressman <galp@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com> Signed-off-by: David S.
