net/mlx4: Fix the check in attaching steering rules
Our previous patch (cited below) introduced a regression for RAW Eth QPs. Fix it by checking if the QP number provided by user-space exists, hence allowing steering rules to be added for valid QPs only. Fixes: 89c557687a32 ("net/mlx4_en: Avoid adding steering rules with invalid ring") Reported-by: Or Gerlitz <gerlitz.or@gmail.com> Signed-off-by: Talat Batheesh <talatb@mellanox.com> Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Acked-by: Or Gerlitz <ogerlitz@mellanox.com> Reviewed-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: David S.
