netxen : fix BOND_MODE_TLB/ALB mode.

Browse Source 
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.
