When we get a stream suspend event force the power down since otherwise
the stream would remain marked as active. In future we'll probably want
to make this stream-specific and add an interface to make the power down
of other widgets optional in order to support leaving bypass paths
active while suspending the processor.

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.

Until now, firewire-ohci exposed only the transmit cycle of the last
transmitted packet at each isochronous transmit complete event. This
made it impossible for FFADO (FireWire audio drivers in userspace) to
synchronize audio-out streams. The fix is to store the timestamp of
each packet in the iso xmit event. As a bonus, the transfer status is
stored too.

-Fix to re-enable the interface [by interface up command(ifup)] while the

-Fix to be able to down the interface by passing the last parameter

-Remove to read 4 extra bytes from the receiving queue after reading a
packet, even though it does not cause a predictable issue now.
-Remove occurrences of transmission done interrupt in order to tx
throughput enhancement.
-Enable IP checksum for packet receiving by setting the corresponding
hardware bit during initialization.
-Relocate ks_enable_int()/ks_disable_int() in order not to declare those

-Rename ks_enable()/_disable() to ks_enable_qmu()/ks_disable_qmu() in
