netxen : fix BOND_MODE_TLB/ALB mode.
o Along with netdev->perm_addr, mac address will be maintained in device private structure. o Device limitation: We need to set mac address when ever interface comes up. In ALB/TAL mode, bonding driver calls set_mac for all slave with bond mac address. But bonding driver set netdev->dev_addr field to its original value, after enslaving interfaces. When ever active slave changes, it swap dev_addr of inactive slave with active. Yet it doesn't notify driver about change in netdev->dev_addr. As netxen driver need to set mac addr when ever interface comes up, it can't rely on netdev->dev_addr field. Specially in case of bonding mode ALB/TLB.
