[PATCH 3.12 125/155] net/mlx4_core: pass pci_device_id.driver_data to __mlx4_init_one during reset

3.12-stable review patch. If anyone has any objections, please let me know.


commit 97a5221f56bad2e1c7e8ab55da4ac4748ef59c64 upstream.

The second parameter of __mlx4_init_one() is used to identify whether the
pci_dev is a PF or VF. Currently, when it is invoked in mlx4_pci_slot_reset()
this information is missed.

This patch match the pci_dev with mlx4_pci_table and passes the
pci_device_id.driver_data to __mlx4_init_one() in mlx4_pci_slot_reset().
