mlx4_en: Setting actual RX ring size
When configuring HW resources, the RX ring size that is passed should be the actual size that depends on number of buffers that we succeeded to allocate. The mask for ring size should also be configured accordingly Signed-off-by: Yevgeny Petrilin <yevgenyp@mellanox.co.il> Signed-off-by: David S. Miller <davem@davemloft.net>
