net/mlx4_core: Maintain a persistent memory for mlx4 device
Maintain a persistent memory that should survive reset flow/PCI error. This comes as a preparation for coming series to support above flows. Signed-off-by: Yishai Hadas <yishaih@mellanox.com> Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
