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.

However, d280ead changed this to checking for non-zero resource flags. Unfortunately, this means that on some platforms, we end up passing '-1' to request_irq rather than the desired result. Combine the two conditions into one so that the IRQ flags are taken from the resource if either SMC_IRQ_FLAGS is -1 or the resource flags specify an interrupt trigger. This restores network on at least the Versatile platform. Signed-off-by: Russell King Acked-by: Eric Miao Signed-off-by: David S.
